I'm pretty contentious with my mom sometimes. Even though she's very supportive and hardworking (sometimes, understanding), I just hate that she asks too many questions, inquires too much, calls too much, talks too much, judges too much, pushes too much, cares way too much about what everyone else is going to say/think and pretends me and my sister should too. She wants everything to be her way and gets very volatile when tide goes against her.
The fact that she's homophobic (and basically paranoid about "weird" people), forced my father to stay with her for years (amidst never-ending tensions and confrontations), took me to some "straightening behavior" therapy when I was a child, forced her religion on me (sometimes still does) and that she probably will not leave me alone when she confirms I'm gay are not helping me grow with a very memorable image of her.
Honestly, I love my mother, but I think that I've been living with her for way too long now.
