Yeah, Andrew Young absolutely pops up.

I know what happened.   He blocked you (or you blocked him).   When you 'BLOCK' someone on Facebook,  they can no longer see you - and you can no longer see them.

Is this the guy we're talking about?   If it doesn't come up for you, one of you blocked each other.
