A few weeks ago my wife was putting our 3.5 year old son to bed. The in usual pre-sleep banter, the conversation went something like this:
Son: Mom, I’m thinking about something.
Mom: Yes.
Son: Can you see the bubbles?
Mom: Bubbles?
Son: Yeah, coming out of my head…bubbles.
…Long pause…
Mom: Is the ‘thing’ you’re thinking about floating in the middle of the bubbles, like in a cloud?
Son: Yeah! The bubbles come out of your head…and in the cloud is what you’re thinking about!
Mom: I see…yes, I can see the bubbles coming out of your head…
Son: Okay, you try to think of something so I can see the bubbles coming out of your head…
