WHY DID YOU DO THAT?

Evan knocked over some of Nathan's toy soldiers this morning before school, and Nathan hollered, "WHY DID YOU DO THAT?"  He was furious at the injustice, of course.  But, oddly enough, even though my nerves were a bit strained, I liked him saying, "WHY DID YOU DO THAT?"  And I thought how I never ask that, and certainly not with that kind of force, even though there are so many things that people do in this world and to each other in which such a question is surely justified.  And there are so many things that I do in which I should also ask, "WHY DID YOU DO THAT?"
