It happened today. I never saw it coming. I figured I had at least two more years. We were waiting in the car line at school. I had the windows rolled down and was clapping my hands to some song on the radio. Lilly (my 3rd grader) reached up from the backseat, grabbed my hands and scolded me. “Dad, don’t do that in front of the school. You’re embarrassing me!!” And so it begins.
