I "ran into" a former professor on Facebook. He and his wife taught young adult literature classes to future educators and I took several classes from them. I loved the classes and got along well with the professors, so I sent them a friend request. This means I am now Facebook friends with several of my former English/literature teachers.
I feel like I should introduce them so they can form a support group. Heh. I was a smarmy, smart aleck. Heck, I am STILL a snarky person but at least I've learned to keep my mouth shut. Mostly.
