When you send friend requests that are never accepted, but you see them accepted by other people in your same circle? Or if you have people who you notice un-friended you? I don't think I take it personally, but it does make me reflect on why. I went to write on my cousin's wall and I guess I'm not on her friend list anymore. We're not close, I haven't talked to her in person in probably 15 years (she's in another state)--so I know I didn't do anything to offend her. And I certainly didn't post anything offensive. Maybe she was just cleaning out her account or something. Just wondered if I'm the only sensitive one!
