So for the last few years whenever my sister comes to visit, she asks me if she can use my computer for a few minutes and it ends up turning into a few hours. Finnally i had enough and told her to piss off and says i dont know how to share, even though her and her husband share everything with me (the last thing they shared was 2 beers of their case they bought for xmas, before that, a year prior they picked me up from work and asked for 20$ for gas money, even though my work was just a short bus ride away), im just wondering if im in the wrong here
