I came across this draft from many months ago. It made me laugh, so I am posting it.
Me: "I can't find my How of Happiness book. The last time I saw it, you carried it in your bag along with your own book."
Trenton: [goes in closet very briefly, then emerges]
Me: "Was it there?"
Me: "That wasn't very long. It seems as though you just walked in, paused for a few seconds, and then walked out."
Trenton: "Oh, I didn't pause long enough! Oops!"
Me: "Ha ha."
Trenton: "Did you own this book?"
Me: "Yes, before it was lost by you."
Trenton: "That's why I used the past tense."
