This morning, my 5-year-old and I had a rather lengthy conversation (the very same conversation we've been having for the past couple of years, really) about whether it's today or tomorrow. I know that the concept of time is pretty confusing to kids, but seriously, how many times can one say, "No, it's not tomorrow yet. Today is today — and tomorrow will be tomorrow!" to a child?
