I got a taste of this yesterday- I was showing students how to use a website where they had to enter their birthdate, and I couldn't get over the fact that people who were born in 1989 and 1990 could be that "grown up". I mean, 1990 seems like just last week, shouldn't kids born then still be in diapers?
Then I realized that I was old enough to be a parent to any of them, and I felt even worse! Oy, I most assuredly need a long nap!
