Facebook update

Well, I took the plunge. In the privacy of home, where I had plenty of time to play with it, I created a Facebook page. I was surprised at how easy it was (taking a good picture was the hardest part--sheesh!), and astonished by how quickly it grew. Suddenly I was getting stuff from all these people. However, compared to my daughter's site, I'm positively plain jane. She's got all sorts of stuff going on there. Evidently, she's some sort of mafia person.
I'm not asking.
Another weird thing? Someone from high school contacted me almost immediately. And, I'm embarrassed to say, someone that I don't remember, even though I looked them up in my yearbook (and they had to tell me their maiden name and that they went to high school with me before I even got that association.)
That's just sad.
Have I truly lost that many brain cells?
