I've just got a friend request and private message on Facebook from a girl I knew in High School. It's funny this Facebook lark - you get friend requests from people you'd completely forgotten existed but as soon as you do you remember them all over again!
I have rather more than the ideal number friends on Facebook which makes it pretty hard to actually follow what people are up to, but it it is nice when you suddenly find someone you'd completely lost touch with. All of a sudden, all those people trapped in school uniform in your memories are real people with degrees and jobs and lives. Very odd!
