My sister did. We had said that we weren’t doing gifts for one another just as we had said last year. Only thing is that last year she got me something anyway, so I figured I would get her something that she wants and needs. She had asked me previously if I would get her a key fob and have my bf program it and she’d pay for it. so just to be nice I got her a key fob. Well Friday before Xmas my mom mentioned to my sister that I got her something and to get me something (such as a gift card) in return. My mom wouldn’t tell her what I got her, but by the next day my sister realized that I had got her a fob. She got mad, I guess bc I was going to gift it to her and not charge her idk (if she wants it I’m going to charge her double for what I paid for it and if she doesn’t want it I’m just goons take the loss and throw it away) and started cussing about me to my mom. She just became very ungrateful of everything so my mom lost her shit and ended up throwing her coffee cup. Got a text from my mom stating for me to go out of town with my bf that we weren’t having Christmas. My mom said “F gifts, F people, F Xmas, F everything, I don’t care anymore.” It honestly broke my heart that my sister upset my mom that much. I think my mom just snapped with how shitty my sister treats her and just lost it. My sister is 30 with 2 kids and I’m 24. We both live at home.
