Several of my kids' friends, including my son's at USAFA have sent me requests, and I always accept them, but I would never ask them. Some I notice friend me and then immediately block me from nearly everything on their page - I'm left going "why did you even send the request then?"
but I think uses it more to chat with his GF or his friends using chat, so I can't see any of those.All I can guess is for some (especially still in HS), it's a status thing to have as many friends as they can!
