Dude, in ten to twenty years you'll be wishing you had a chance to be more immature. Remember, You're only young once, you can be immature forever. It's a gift, not a curse.
I'd post something deep, snarky, or original here. Or maybe I'd whore myself out by posting a link to my website. At the end of the day though, I'm too lazy to copy and paste an interesting quote from someone else or create original content to link to.
