Well, i think you might be stressed out about this
because your friend has something you don't (yet): 2 inches in height. And given your nick, it would seem you're a pretty competitive guy, so this difference might bother you! Listen, we're all different, sometimes you'll meet peeps that have something you don't, and sometimes you'll have stuff they don't. you might try to remember that what you see isn;t always as important as the stuff you cannot. The stuff inside.
If you and your friend have been good buds for a while, you might try to stay focused on that, that's what's important, that's what's always been there,instead of couple of inches in height.
