That's why Richard Smith's claim that Oswald was "never humorous" is absolutely ridiculous because even the most serious person is capable of cracking a joke.
Good point you made about people possibly not coming forward. Oswald knew people during his lifetime so we have no idea how he acted around certain individuals on a daily basis besides his co-workers that really didn't know him to make an accurate assessment of his personality.
And it's a known fact that people act completely different in a work environment than when they are around their closest friends.
Actually he did act differently that day
1) He 'reached out' to Kennedy while at a distance
2) He got 'up-close & personal' with Tippit
What a guy!
Try as you OAKers may, you'll
never humanize the cold-blooded little cockroach
No sane person gives a rat's arse about Oswald's alleged 'personality' beyond what ultimate effect in had on Kennedy & Tippit
