I have a theory as to why captain Picard is so aloof and doesn't generally let people get too close...
One of two oldest friends, Jack Crusher.
First time we hear about him he's already dead.
Second of the two oldest friends, Walker Keel.
His ship gets blown up in the same episode he was introduced in.
Alright, how about another old friend, captain Donald Varley?
Uh... His ship blew up. Right in front of eyes of the TNG crew.
It sounds about right that character who lost every best friend so far subconsciously connected their deaths to his friendship with them and figured it's better to keep people at a distance, which would, in his mind, either protect them entirely from the same fate, or at least make it a little bit less painful for him.
I mean it probably isn't the ONLY reason why he does that but it does make a pretty good explanation, doesn't it?
