Wheres the lid?

Today O. helped himself to a package of dried bananas from the pantry. He then precedes to loose the lid. When we asked him where the lid was, he looked for it awhile, and then seemed to get over an urgency that we had about finding the lid. He then sits down at his keyboard, turns it on and starts playing. When asked again where the lid is, he says.. “I’m playing a song about the lid”.
