What is a shower, you may ask? Well, primarily it's a device in which one cleans himself thanks to running water and a drain. But, that's not the type we're having for you. It's when all of the people who already love you get together and SHOWER you with love, and affection, and excitement and gifts, if they so choose.
There's going to be a lot of good food, which I know you'll love. There are going to be some fun games too. But not "everyone come play this game" game... more like "anyone can play this if they want to."
In one game, your guests can cut and paste together pictures of what they think you might look like, using your Mom's and my baby features. Here's a test your Mom did on the computer:

This game absolutely frightens me. I hope you can see why. You kind of look like a monkey wearing someone else's face like a Mexican Wrestler Mask. But that's okay. It's still a cute idea and should theoretically be fun for anyone who wants to play!
We're also doing a little illegal gambline and wagering. People are going to place bets on the date and time they think you'll be born. But, don't worry, it's not for money: it's for chocolate.
I like chocolate, and I love you: so I'm going to go ahead and be the first to wager. I think you'll be born on March 3, 2010 at 7:30 pm.
Hopefully I win some chocolate. But, either way I win because you will be here finally!
Now, onto less expected precipitation. I don't want to say too much so as to not gross anyone out, but let's just say that if your Mother were currently any setting in the Harry Potter series, she'd currently have to be called the Leaky Cauldron. She just discovered that this morning! It's definitely weird, but it's completely normal and only concretizes the idea even further: you're coming, and you'll be here in about 2 months...
on precisely March 3 at 7:30 pm! (c'mon...Daddy needs some new chocolate!)
