I bought something that was litterly $0.99 with my mom's credit card without her knowledge and even though it was just a dollar, I cant help but feel guilty...I dont know why, I mean I thought I'd care less but obviously I dont....This is weird for me, I mean come on...it's a dollar...
Because you know stealing is stealing no matter how obsolete the amount is. That is very good to know and will make you a better person. Tell her you bought something with her card and you feel bad. She wont be that mad I promise.
Maybe because you care about others and you realized that you did something wrong. Most likely your mom would not mind it but remember to not steal in the future.
