Tough Questions

A typical conversation with Bryan, my three-year-old….

Me: Bryan, Look. It’s raining.
Bryan: Why is it raining?
Me: Because there’s too much water in the cloud. And when there’s too much water in the cloud, water drops fall and becomes rain.
Bryan: Why is there too much water in the cloud?
Me: Because water evaporates into the air and eventually end up in the cloud.
Bryan: What is “evaporate”?
Me: ….
Bryan: Why is water falling from the sky? Is there a big hole in the sky?
Me: …. Um, no.
Bryan: Is the sky hard (as opposed to soft)?
