Yesterday E wanted to go outside to play. It was a truly arctic 58 degrees, and raining outside so I told him he couldn't go without his jacket. He looked for it, and couldn't find it. He asked me where it was (I'm mom, keeper of all things missing), I told him I didn't know. He looked in the closet, his room, my room, etc. Then came and said. "It's invisible", at which point, he put his hands in his pockets and proceeded to get ready to go outside.
