Why do you wear a mask? I politely asked a man who seemed urbane and intelligent.

He went into stunned, outraged shock for a few seconds and shot back with: MIND YOUR OWN BUSINESS!

Then realised that was lame and asked: Why don't you?!

Because they don't work.

Was going to add more about the dangers of wearing one but he dashed away, so I called out "Keep the narrative going" after him.

So much for men being rational and unemotional.
