Talking to strangers

From Cindy’s Facebook:

Apparently, I’m the kind of stranger you want to confide in at the grocery story when you’ve just had ALL OF YOUR TEETH removed. Sweet little old lady in the baking section was wearing a mask over her mouth. All I did was smile at her. She pulled the mask down to reveal a horribly bruised lower jaw. “I just had all my teeth pulled out,” she said. “Upper and lower, but he put my dentures back in on top.” And she pointed to said dentures. “Oh! That must have hurt!” I said. “Nah, he numbed me up good.”

Question: Do you talk to strangers you encounter in stores, businesses or in other public places?
