I was the one who invented the "Hello, My Name Is" badge. A huge contribution to reducing world discomfort. We hand them out at The Summer Party. You're encouraged to write your name large.
Add things if you want: "Big personality". "Not big personality". "I'm listening". "Do go on". "Former US ambassador to Nigeria". "I'm with his lordship here". "I study earthquakes. You're standing on one." "Nicest person on earth".
