What we forgot

The other day as we left his daycare, we almost forgot the latest in Will’s succession of Scratchies (currently a purple My Little Pony originally named Twilight Twinkle). We got out the door and were buckling up when I remembered, and we had the following exchange.
Mommy: “Uh oh! Guess what we forgot!”
William: “Your calendar?”
This from my three-year old. Perhaps we need a less structured life.
