After my stroke, my manners were slightly off. I was told to ask my friends what was different about me.
At an ice cream store with a friend, they were about to close and were giving away pastries. I went up to the counter and took one. When the clerk tried to engage me in small talk, I just walked away.
“See?” said my friend afterward. “You should have thanked him. And chatted a little. He was giving you a free pastry.”
Do you have etiquette stories?
