Reminds me of "Great minds discuss ideas; average minds discuss events; small minds discuss people".

I have read this on Quora 10 years ago, esp. when i was in a highly divese neighborhood, like: Poor people, doing-well-people, refugees, unemployed, but also academics and wealthy. So i could jump segments very often in a week, and this saying turns out to be absolutely right, in my perception. Since then, i'm looking/hearing very thoroughly when being in a group situation.

A quote discussing the behavior of people?
