Say if you were friends with Michael and he say your his GF and then he says I was playing I didn't really like you but then he starts always asking for you?
First, i'd be "Why?" then he'd say "I just dont wanna say it to everyone, you know?"
second, i'd be all like "make up ur mind, will ya? and why even ask if I want to be ur gf? you already know the answer." Then we'd hug and i'd be taken to his house to have a romantic dinner :)
