Too old to stay up late!

Joel and I had some friends over last night for lasagna and to watch the movie Elf. It was great and we had a ton of fun but we stayed up later then normal. I think we went to bed around 1:30 and now we are realizing today how we just might be too old to stay up that late. Joel is on his third cup of coffee (at noon) and I am ready for a nap already. Pretty pathetic!!
