I’ve been doing cartoons for a long time.  In the family strip I do, The Buckets, I’ve had lots of time to study various human traits and weave them into the humor.

You may have noticed the same things I have, but because of non-cartooning  reasons.

Stuff like- People rarely seem to understand when the humor is about them.  And, people seem to hate worst in others the traits that they don’t like in themselves (and that often define their own behavior)  And, of course, nobody much likes it when they have to think about the psychology behind the comic strips to get the gag.

And cartoonists are apparently full of themselves.
