Why do people keep trying to talk to me when I go out in public? Don't they know I'm an introvert?

My husband is like that. He doesn’t like talking to people including his family most of the time.

they do NOT know.. maybe you need a tee shirt?

Hmmm you must smile a lot in public or have a youthful look. People like chatting with happy people
I don’t like strangers, so I frown and make zero eye contact
So
If someone actually talks to me, I know they are coo coo cray cray.

Maybe you should wear a T-shirt saying introvert or write it across your forehead
