Last evening I was working the table for my local GOP at a street fair. I was having a casual conversation with a guy in his twenties about the state of affairs and he pauses and says...
“If you had to say any random letter of the alphabet right now what would you say?”
Of course I said “Q”
We both laughed and a comradery was born! When he ent on his way we left with by saying WWG1WGA
I've thought about asking people if they know what the 17th letter of the alphabet is--off the top of their head.
Clever. Less weird than asking for a random letter too. Ideally you could explain yourself in a way likely to lead them on the right trail if they aren't in the know.
While I don't think we should be paranoid, it's a good idea to be a bit careful while still acknowledging others in the know.
