. . . when, in his presence, you are telling your spouse about a blog post you read and the author's great response and somebody else in the story's not so great (though typical Polish*) response to a scary situation. The child does not understand much of what you have been saying. You finish the conversation with, "It's kinda too bad."
Said child pipes in, "It's kinda too bad? Why?"
That's a three year old.
But you can be grateful if this same child usually follows up his "Why?"s with "Because?" and is satisfied when you respond, "Yes. Because."
*Though it happened in the U.S.
