Every morning on our way to kindergarten with my daughter, we see first graders walking to a nearby school. It's fun to observe them. I'm normally only half awake, it's pitch black and often freezing cold, but the students seem to be full of energy. Those who walk together with friends are laughing, talking loud, and surprisingly often mimicking shooting sounds.
Pretty sure that 30 years ago, me and my friends looked and sounded exactly the same.
