Funny human rituals

[Little lunch]

I think it's funny how men nod their heads when greeting men they don't know but do a reverse nod when greeting a man they do know.

I also think it's funny that, when shaking hands with a man, it's always the little people that have the strongest grips.

Or when people trip over something and always look back, not to see what it was that tripped them, but to divert other people's gaze from the tripee to the tripper, because it's the culprit, not their clumsiness.
