You know you're old when....

• After telling your students that you graduated high school in 1999, one of them raises their hand and says "I was one year old then."


• You go to sleep at 9:15 on a Friday night


• Your knees crack when you get up in the morning


• You look down and realize you were driving 55 on the highway and you were in the fast lane


• You find out that students starting college this year have never seen one of those giant Sears catalogs

All of those things happened to me this week. I think I must be getting old.
