Well, back from shopping...
Santa pants are jeans for each family member which are wrapped and addressed as "from Santa". This sounds dumb, but it's complicated. See, we didn't 'do' Santa, until my littlest brother, who has Down Syndrome, went to private Catholic school and they told him Santa would be bringing presents. So he got so excited and wouldn't believe us that Santa doesn't... anyway, that year Santa showed up with gifts and all, and what the brother got was pants.
So to reinforce the idea that the presents are really from Mom and Dad, from now on we say "Santa brings pants" and hand out Santa pants. It's a lot of fun and a good way to get a new pair of jeans.
We attempted to fetch the inlaws from the airport, but their flight out of Charlotte was canceled. Sooooo.... they're getting flown to Reagan Nat'l and bussed up to Baltimordor.... late tonite. I feel so bad for them! My MIL is busy making 'friends' with everyone, I'm sure. My FIL is probably sitting there with a clinched jaw.
Merry Christmas!
That sounds like a great family tradition you have there.
