As of 9:17 p.m. P.S.T., I'm an uncle. No great accomplishment on my part, I realize. On the other hand, you're going along in your life, doot dee doot dee doo, and stuff happens and, sure, you get married and whatever and that changes things a little, but you're still basically the same person you were when you were fifteen and whatever, and then all of sudden, BAM!, your sister has a baby, and all of a sudden your dad is Grandpa George and your mom is Grandma Linda and you're Uncle Paul. And you're like, holy crap, Uncle Paul is that guy who has been married to Aunt Paulette since before I can remember, that's not me, but the universe is like, no dude, that's totally you now, this is what happens in life, things change and it's totally freaky.
Anyway, welcome to the world, small child. Be well and do good, and try not to be freaked out about how your mom is actually my little sister.
