Most Helpful Girl
Pf don't sweat it. If people wanna be idiots let them be idiots. It's way wrong to criticize someone over something they can't help like height. And even though she is choosing to wear heels it's a free country, right? Anyways if people choose to talk just tell them that it's because she's wearing heels. And you should also tell them that it's rude to criticize someone over height anyway.

I think you shouldn't care what others think, say or feel about YOUR relationship. Irregardless of 5" heels she would wearing, tell her how great she fucking looks and not simply act but KNOW the girl beside you is the greatest thing in your world.
