I was heading out the door to take Zoe to school and I couldn't find my keys. I realized I had left them in the backyard the night before when I mowed the lawn. On the way to school, this is the conversation Zoe and I had.
Zoe: Mom, why were your keys in the backyard? Mom: They were back there from yesterday when I was mowing. Zoe: But, why were they back there? Mom: Because I put them back there. Zoe: No, Mom, WHY?!! Mom: Zoe, I don't know!
