Looks like some of the stuff a few of the "Goth" types at high schools are wearing. One of them made me nervous last year, he came in wearing black from head to toe with a long black old West flappy black coat to his feet and long black dyed hair, etc. With all these shootings at schools that was all I could think of, and with our going there for blood drives made me nervous till we left. Most of the kids are well mannered, in today's way, but the Goth look is way too far out for me.
And yes, I noticed that the teachers were aware of him every moment he was in the gym.
