My mom wants a $400 MacBook but I don't want to give it to her because she borrowed $100 for me.
Do you not trust your mom to pay you back?
She is like that, she cares more about others than me. I'm sick of it.
It may be unfair for your mom to borrow money like that, but she is family and you should help her when she is in need. She will pay you back, and your relationship will only get better if you are comfortable like this with borrowing.
I can't believe you. She's on drugs and I'm the one who should cater to her needs. I hate her.
Honestly I wouldn't be so quick to judge. Your mother may be using the MacBook to start looking for a job. You should try helping her to get better and give her a chance to redeem herself first.
