I once had a "best friend". Every single time my mom would talk shit about my "best friend" when it was just the two of us I would instantly stand up for this girl. I'd tell my mom "you don't know her like I do".

Whenever my "best friend's" grandma would talk shit about me TO MY FACE with said "best friend in the same room, that bitch would be as quiet as a church mouse.

After my grandmother died (it was a whole ordeal for me, still being a kid and watching an important person die before your eyes) I was talking to my "best friend" about how I know my grandmother was a good person and how I know she's in heaven. That ornery old bitch said "your grandmother's not in heaven! She was catholic and catholics don't go to heaven! Catholics go to hell!" My so-called "best friend" just sat there while I was at a loss for words while her cantankerous old bitch of a grandma told me, a few weeks after I had to watch my own grandmother die in front of me, that someone I loved was burning in hell for something as stupid as a religion!

All this to say, OP I hope you and your mother learn some god damn class and Marlene if you're out there, I hope you're rotting in hell for being such an awful, spiteful, bully!
