Sister KC, you're right to say don't focus on the kid, but the brother you hold in high regards is on the path of bad medicine. If you examine him closer, you would see the bad path he is on. The drum is sacred and is for healing. Don't be a hang around the fort Indian of uncle BIA.
Just need to to state an observation fron First Nations People perspective. I have seen that look on that young man's face many times. I would venture to say that is his first encounter with a Native American, he doesn't know how to react to the situation and he's both amused and fascinated.
I've seen these kinds of reaction when I was on the Pow-Wow trail in my younger years. The closest this youngster has been to a Native American is the TV. Oh, yep we have shills too and you're looking at one confronting the youngsters.
