True, I never basked in the glow of the high school stage. But I have fond memories of working behind the scenes, as stage crew. Dressed in black, I rushed the bed onstage for Tevye's dream sequence in Fiddler on the Roof.
I've also spoken with many people who weren't involved in theater at all but can still — for some reason — remember the shows their schools performed.
There's just something about the high school stage.
