You're welcome, Jon - I think the reason why people often don't
   have friends, is they forget how to be a friend. I remember kids
   in school who never learned how to be a friend - they usually
   ended up being bullies as a substitute for being a friend. But
   it was the odd ones like that that got me interested in
   psychology - "why are they like that?' "How can you get through
   to them" - and usually, they just wanted someone to really take
   the time to understand them and let them be themselves, someone
   who was honest that they could learn to trust. "
