Thanks Punkey. I've learned a little bit about what he likes to do when he's not working, but not really enough to have any basis to get together.
From what I can tell, he is available. Like I say, even though I had tried to "ask him out" -- I'm really just hoping for a friendship. At least for now.
But yeah, the age difference is huge. Still, I get this feeling that he is an "old soul" and that we may have some connection.
