Serious boundary? He put tits in front of my eyes. Am I supposed to remember to keep my eyes pinned to the floor when out in public? What a terrible way you must live.

I’m afraid to say, that if you want a boundary, go home. Otherwise, accept that you’re in public, and people can and will speak to you.

Also, you’ve just justified being violent in response to someone making sounds with their mouth. I bet you’re a calm person to be around, when everyone does what you want.
