Yes, I have seen some weird possible connections on FB. All from my older son's 1st grade class in AZ, because I am friends with the kids of my friend there. Those kids went to a different elementary school than my son, but they all became (real) friends in middle school and high school. It's weird that the same group of kids he was friends with at age 7 became very close friends of my close friend's kids when they were teens. I also have seen some names I haven't thought of in years, as I am friends with a few people from the high school I went to here in MA, before I moved. I didn't graduate from this school, and some of those connections go back to my own preschool days. I haven't connected with any of them, though.
