Most Helpful Girl
It wouldn't make or break my decision. And I am not saying that I'm not shallow in the least, or that I never think about people's appearance, but honestly, if you're a great guy, especially if you're funny (but not in an asshole way) I would date you. Bonus if you're attractive. Short doesn't make or break attractive.
Plus, if a girl won't date you because you're short, is she really the kind of girl you want to be in a relationship? Sounds like a bitch.
I don't think I'm uncommon in this. I don't care about shortness.
