pending on facebook?
the appearance was that he was friends with 8 new people, it wasnt a comment he made on another person. He is in bold letters and its his new status of his new friends
It is possible. Just because they're not your friend does not mean that they don't have other friends. maybe they commented on your friend stuff and it also appear on your news feed. that have happen to me alot of time but yes it is indeed possible.
