Yeah... That song is HYSTERICAL, Marg!!!
I recently got a friend request from my high school nemesis. This girl followed me through HS and about 3 years of college, scoping out the guys I might be interested in and snatching them up. Fortunately for me, I was keeping my eyes open. If the guy wanted HER, I probably did not want HIM.
...Imagine my shock when, after I left my ex, I found out he'd dated her... EEEEE!
But I digress. I have a lot of "friends" on fb from HS, that I just do not talk to except for Farmville. They're carefully blocked from almost everything (well, everyone is - except for those I allow certain permissions to). FB tools are wonderful, if a little unwieldy. You just have to take the time with them...
