It could just be a bug. A friend and I tried exchanging friend's requests a couple of weeks ago. I would send a request and he would never receive it. He would send a request to me and I wouldn't receive it... Neither one of us had a full list at the time. We finally gave up after several tries.
BUT, the next day when I logged in... there was his friend's request sitting in my box. So apparently, there was some sort of bug or a very looooong delay.

This happens to a lot of ppl. If you need to find a friend, you can always both be friends with one of your friends, then meet up. Make sure to log off. Dumbo VMK bugs
