My son threw his shoe on the roof...
When it got stuck, my wife admonished him and asked, "WTH did you think would happen?" He didn't respond.
As an understanding father, I sat him down and explained that, if he finds himself in that position again, he should be clear that he's a strong Humean skeptic and that it doesn't really matter what he thought would happen because he couldn't actually know without perceiving it empirically.
