hmmm...I have had this kind of thing happen and just clicked ignore and hoped for the best. you can always claim ignorance if he ever brings it up, but he isn't likely to surely. or just say that you really liked it at first then stopped really using it or something like that. I had this dilemma when my dad sent a friend request. since he is now on I have had to moderate some of my status updates etc...so don't do it if you are not comfortable with it.
