answer:You know, in the old days, you might call him up (on the phone) and tell him you wanted to know more about his experience in the other country because you are interested in doing that kind of work, as well. Then you might talk, or meet for coffee and talk, or whatever. But not its Facebook, and its as if there is no social life outside of Facebook. I wonder how long it’s going to take people to catch on that the social life inside of Facebook is really quite different from the social life we have in the real world. But I don’t see why you can’t friend him and send him a note saying the same thing. “I heard you talk about your work and I’m interested in that work too, so I hope we can friend and I’d like to have a chance to find out more. Do you have any pictures of what you were doing?” Then you become friends and then you work it from there. I’m sure he’ll catch on pretty quickly that you are interested in him. You “like” him. Maybe he still thinks of you as being off limits due to being three years younger (or whatever). But thems the breaks. In a few more years, it won’t matter so much. But you don’t really seem to know him yet, so who knows what will happen when you get to know him. I hope he turns out to be as wonderful as you think he is.
