Everyone has that friend who's every day like 'I hate my nose I hate my nose I hate my nose.' You either need to come to peace with it and be like alright I hate it but it's part of me - or change it. So I'm not against plastic surgery I'm against plastic surgery when it doesn't really need to be done.
I don't think your ability to fight has anything to do with how big you are. It's to do with how much anger is in you.
