what spring to mind here is this.
If friends or peeps have not bothered to get in contact after many years, maybee they don't want to.
Maybee they were not the good friends you thought they were.
Sometimes the past should stay that way.
I have kept in contact with a few schools friends from late 70's, but thats it.
I don't miss the rest off them, so hey, life goes on, time stops for no one.
just my input on a wet afternoon.
cheers
