Near-Earth Object

The Boy (3 years old): Daddy, one day, when I’m an ice cube…

Me (35 years old): Wait, you’re going to turn into an ice cube?

Boy: …Daddy, when I’m an ice cube, I’ll melt.

Me: Well, when will this happen? When will you be an ice cube?

Boy: In two weeks. And I will melt.

Me: Are we talking metaphorically here, or are you literally going to turn into an ice cube?

Boy: Trust me, Daddy.
