Chances are there is someone telling her this right now. I heard once (can't remember exactly where) that for an attractive woman there are 11 guys trying or interested in dating her at any givin time. Mabey a guy friend of hers, mabey a friend of yours, co-workers, someone on the train if she commutes every day, school if a student, guys at the gym, I could go on.... So guys if you have a girl and your not telling her she is beautiful and someone else is...what do you think will eventually happen?
