The Unbreakable Man Laws

Specifically, if there is nothing between you and the woman, then buy her all the drinks you want to (I buy my friends drinks), send flowers (still not a fan), continuously invite her out even after she cancels (hey, takes more than two to have a party and no one likes a sausage fest). YOU have decided that you are not interested in this person as a potential partner, it does not mean you can not legitimately be friends with her.
