I have a certain set of rules I try to live by. Rules that have always served me well. Until now... Rule one: Don't have sex with someone you work with.Rule two: Don't have sex with your friend's ex-boyfriend. Rule three: Don't have sex with your best friend who also happens to be the same ex-boyfriend of your friend.Rule four: Don't ever, under any circumstances, fall in love with your best friend. I guess it's safe to say, I officially broke...
