I spent 4000$ on my mom's credit card with no remorse and no intention of paying it back
Why did you do that with her card?
She is so stingy and never lets us go out with friends, I just threw a party for everyone.
She is going to have to pay that back. That is stealing and it's wrong to do that to her.
She can afford that bill, I am just doing this to help her loosen up.
Even though she might have the money, it is not right to take advantage of her to throw a party. She will feel used and unloved by you.
