Have fun with strangers. Whenever you're out of the house, you will come across people you have never met before. What fun it is to interact with them. You can try to guess where they are from, as I did with a gas station attendant. "Are you from Africa?" yes! "East Africa?" wide eyed "yes!" "Ethopia?" Bug-eyed: "100% correct!"
We high -fived and his associate walked up. "Do you know the capital of his country? He knows I know. Do you?"
Associate says dejectedly, "Shit" and turns around walking away. I say "Addis Ababa". Clerk says, "I am from Addis Ababa!"
So began my guessing countries of origin, and often even cities.
To Costco food server: "Namaste". He replies, "Namaste." "Let me guess. Are you from Mumbai?" Mahesh replied, "Yes, I am from Mumbai." Lucky guess, but even if you're wrong, it's fun. When you are right, and I have been right a lot of times, it is overjoyful.
Other lines: (Put your hands on two people's shoulders at the table): "Keep it down here; we don't want any trouble."
To a big bruiser, placing your hand on his shoulder in a friendly manner: "If there's a rumble, I'm on your side." Invariably I get, "You got it." Another new friend.
