This one is from a tweet posted by Orlando Sentinel columnist Scott Maxwell. A reader wrote to him:
“Back when I was a pre-K teacher, I was also a responsible gun-owner. Never had a shooting, but if I had, I couldn’t have managed 20 kids AND a gun. The two hats should never cross.”
This is a mashup of “wearing two hats” (to hold or function in one position or role) and “crossing paths” (to meet someone by chance and not by choice). A tip of the hat to Tom Justice for seeing this one and sending it in.
