(I give tours for prospective students and their families at my school. In the school chapel, there is a plaque commemorating when Martin Luther King, Jr., gave a speech there in the 1950s.)

Me: “The chapel has been host to a number of famous speakers, including Martin Luther King, Jr., as you can see here.”

Parent: “Oh, was that before or after he was assassinated?”

Me: “Uh…”

Daughter: “Mom!”
