I live in a large family and everyone is way taller than me. Like really, I'm 17 and my 12 year old sister is 3 inches taller than me.
So I have few things I say when people and my friends see me standing by my family.

"I am a midget in a family of Giants."

"Maturity speaks louder then age and height."

"I'm 5"7, but considering my situation, that's not very tall."

And finally:

"I hate being short."
