You're 5'4"!? Heh, no wonder you look so skinny from where I'm sitting. I suppose that's appropriate, anyway, be careful the way you stand. Your shoulders get too tense after a while and your spine goes in. If you keep standing like that, when you're older you'll be in a lot of pain.

But then again, you don't dance, so I'm sure you'll be fine. But still take care of your body while you're young.
