  • One morning, my brother brought home a box of Krispy Kreme donuts, and left them on the kitchen table.

    My mother and I sat at the table and looked out the window, talking about birds and how smart crows and ravens are, and how when I see a group of them around sunset, I think of the word crepuscular because they are active at dusk.

    My mother is a visual learner so I wrote the word down for her to see. We finished talking, and left the room.

    My brother came back and saw the note on the table. He thought it was a comment card for the donuts. He assumed it was a compliment, as in "Thank you for the donuts. They were very... crepuscular."

    Now crepuscular makes me think of corvids and donuts.
