Sounds like FB is recommending people he thought he was already friends with, but who stealth-defriended him somewhere along the way.

Exactly. If I look at the recommended friends page, people who defriended me are often near the top (probably because of the high number of mutual friends).

In this case, "he" is a "she", btw :-)

"... FB is recommending people he thought he was already friends with ..."

That would sound right. Must friend a lot of people not to notice silent drops. FB gives you a numeric number on your friends list.

Or just not care enough about Facebook to keep track of the number - which is the case for me.
