This girl I just talked to got pissed off at me when I jokingly said "it's all in your head" when she claimed her left one is bigger than the right. She said she talked to the doctor one time she was in there and brought it up. The doctor said there's nothing visually nor medically wrong with her. Is it even possible for one boob to grow bigger than the other? I'm trying to figure out if it's true and if I REALLY could of hit a sore spot despite the fact I meant well.
