My wife and I attended high school prom last night. She was a faculty chaperone and I was, even though we have no children there, a parent chaperone.
Fortunately the specified dress for the adults’ was business formal, so there was no need to go out and purchase or rent formal or semi-formal wear. I used to have tailored formal wear (I looked sharp in the white tie, and tailcoat), but that was when I was in high school and my body shape has changed a bit since then….and the clothing was long ago sold.
I always like doing this kind of thing because it gives me the chance to see young people nearing the point in their lives where they will be heading out to make their mark upon the world. And, I’m comforted because I think the mark will be good.
