The key is in the echo. A gunshot, generally, is a brief burst and then a brief echo. A firework, on the other hand, explodes and echoes back, back, back. It swallows and keeps swallowing. Even if the light never touches a sky you can see, the echo is what to listen for. I don’t remember how young I was when I learned this, or if I will teach it to any children I may one day have to look after. We all have a right to keep the people we love safe.
