There might be several hats for a person – when you make a sale (optimistic, pushy, presenting the positive) vs. when you do an audit (critical, negative, holding your stance, trying to prove things).
It’s a different thing to be with a friend and with a family member.
With a stranger in your country and with a foreign one.
With someone your age vs. someone with a totally different age.
Hats are good – they force you to become flexible.
That’s why I consider, generally, that traveling is good for the mind.
