I'm thinking of faking lung cancer during high school
Is there a reason you want to fake lung cancer?
It's a bit of a long story and to be honest it involves a girl.
It is okay to want to impress a girl you like but you shouldn't pretend you are sick to do it. It is wrong and people will feel betrayed if you do.
I was hoping she would feel guilty for cutting me out of her life.
I can assure you, telling someone you have cancer when you don't is not the way to one's heart. You should try some candy, flowers or a nice dinner instead.
