Well, my mom was a troubled individual. She'd lock me in a dark closet, put me in cold showers (thankfully, I got to keep my clothes on), spank me with a belt, pour hot sauce in my mouth, slap me, etc. I don't think it was to encourage to behave, because even if I said one swear, out comes out the hot sauce.
I'd ask her to adopt you, but she just gave birth like two years ago so she has to take care of my sister. Also, she doesn't live with me
