If you were at a restaurant and overheard a group of three girls at a table
Girl 1: how do you guys just eat anything and stay skinny?
Girl 2 & 3: *laughs*
Girl 2: are you serious? You can eat whatever you want if you just throw it up afterwards
Girl 1: are you kidding? That's so unhealthy
Girl 3: like being overweight isn't? Trust us it's fine..and you should start doing it too
Girl 1: *self conscious*
