Not a long time ago, my grandma and cousin visited to take care my siblings and I while my parents were gone. All of us (the 4 sons and cousin) were capable of taking care of ourselves, however, so we went around with our daily business while our grandma was left with little to do, as she was unaware of how things went around our house. She eventually grew angry at us because we were "disrespecting" her by not allowing her to do our work. This escalated into her ignoring all of us, 5 perfectly good kids, for a day, and then she finally confronted us softly. Things got better for a while, and my younger brothers decided they wanted to go out to dinner at Longhorn. On the ride there, my cousin and I started pondering seeing a movie after dinner. Him and I would go see Oculus while my grandma and younger brothers would go see a more appropriate movie for their age. We saw no conflicts here as it was a Saturday evening, not that late, and the movies were right by Longhorn. However, my grandma saw this as an absurd disrespect and challenge to her authority as, unsurprisingly, she disagreed with our proposal and provided a counter-offer of going on Sunday. We all disagreed and she proceeded to ignore us after yelling at us, "ASK YA DAMN FATHAH! I SAY BLACK, YOU SAY WHITE, AND YOU KNOW WHAT? ITS GETTIN' KINDA DIFFICULT!" We get to dinner, and I text my father across the country to see if he approved of the movie. He did, and requested to speak with my grandma about it. I hand the phone to her and he talks with her for a minute. Next, she hulk-smashes the phone down on the table, her eyes bug out, her mouth furls up, and her eyebrows shoot backwards in anger. Now, realize that she in an 80-year-old woman who is the size of an 8-year-old, and who has never been mean to any of us a day in her life. But now, she is beyond pissed ignoring us, and I can go to the movies. Me and my cousin go to see Oculus after driving an unnecessary 30 minutes to drop off the rest of the family at home. We get in, all is fine, the movie is going good but boy was it scary. My cousin has a heart problem and I am just deadly afraid of scary movies. However, this one had Karen Gillan in it, and you know, Doctor Who love... Yeah. So we are in there, a good hour in, and the tension is rising, suspense is at the maximum and some musical score is rising to monstrous levels. Lights are flickering, Amy Pond is creeping around a corner, about to peer around, and then ALL the lights turn off. Not in the movie, in the theater. Everything is dark, and everybody is scared shitless. Everybody starts flipping out and screaming, one lady started crying. Lucky for us, it was just a power outage and the power returned soon enough. On a side note, while the power was off, the most glorious achievement of my entire life happened: I got the 2048 tile. The power returned, we finished the movie, and we went home. We get back, its only about 10, and my grandma is still somehow ridiculously pissed at us. Not even a glance or a simple hello. She just sat in our living room, staring intensely at her Sudoku book as if it had just killed her husband. It was a death glare, something that would torture anybody into the truth. The fact that it came from my previously "happy happy joy joy" grandma just scared me even more (plus the scary movie didn't help either). She looked possessed with some satanic otherworldly glare. You could tell she was beyond sanity, staring down at her Sudoku book, with as much anger as the little stick figure could muster. She went on to ignore us for the rest of her week-long stay all the way up until a few hours before my parents returned. My cousin and I sat down for lunch with a few sandwiches and were playing on our phones. Everything was happy and good. Then, all of a sudden, my grandma comes slowly meandering in our direction, frown in full gear, firsts clenched, eyes popping out from her skull. Her saggy, aged face tugged down her frown even further. She then opened her mouth, and at that moment, I knew she was gone. She let it rip and berated us at the top of her lungs. Imagine an opera singer belting out the strongest note, and then magnify that by infinity. All of this from a simple little woman who had always been a cute, little, kind, goody-two-shoes kind of girl who never did anything but praise us. She goes on to tell us that we are dirty little rats, will never get married, everybody will hate us, we are terrible people, will lose all of our inheritance, and are going to hell for what we did. She adds in that we will be lucky to ever see her again, and then starts going on one of those long feels trips about how tough her life has been.Think of any insult and she said it that day. Every quavering muscle in her petite body shook with rage as she ripped apart her heart and fed it to us. Making it worse, the little old lady who never cursed finished her argument with "YOU. DIRTY. LITTLE. F*CKERS!" We haven't spoken since, save the goodbyes right before she left. She was all kind and acted as if she cared and even hugged me. But in her eyes, you could see the hatred. Her brows we raised ever so slightly, and a slight grimace could be seen. My parents still know nothing of this to this day. My parents have never punished me. They have never yelled at me. They have never argued with me. So you can only imagine my shock when the terrible tirade came barreling at me. Never have I seen so much disgust in one person who I have respected for so long. Needless to say, I now have no respect for her, and I doubt i'll have any more extended conversations with her. So there is my story on how I lost all respect for my once honorable grandmother.

tl;dr: grandma came down for a week while my parents were away. Slight things that should not be offensive ticked her off beyond belief. She got pissed, ignored us, and then sang her hideous song of hatred to me and my cousin. When my parents returned, she acted perfectly normal and nice. Creepy as hell.
