That’s an interesting insight into human behavior that I never thought of.

I remember a long time ago, I was at Boston South Station with my then-girlfriend. We were looking at a monitor on the wall trying to spot when our train home would come in, and I pointed at it to show her.

A nearby homeless woman then informed me that it’s unpolite to point. That always stuck with me. She was standing right in front of the screen…but now I know, I should’ve used two fingers.
