Kid: “How come on my math sheet you wrote that I had to write the answer in hashtags?”
Me: “No, honey. Not hashtags. NUMBERS. You were supposed to write a matching NUMBER sentence.”
Kid: “But you wrote hashtag.”
Me: “Well, believe it or not, back in the olden days– the days of yore, if you will– THAT was a symbol for the word ‘number!'”
Kid (skeptical): “Well that’s just weird.”
