I'm thinking of the oft quoted phrase that men are scared women will laugh at them and women are scared that men will kill them.
I'm in my car in a supermarket car park and and a bloke nearby is shouting really loudly. I actually think it's light hearted banter with someone he knows, and my sensible brain knows I'm not really at risk.
And yet, my heart is racing and I have a sense of fear. I've slunk low in my seat to avoid being seen.
everyday behaviour that men probably don't even notice.
