Feather Lakota Sioux

Seven years ago I was called to make the Sacred Native American Indian Chanupa (Peace Pipe) It has brought me down a long road, I have been gifted Eagle Feathers from Tribal Chiefs, and I am now very active in the Religion and Culture. I attend many Sweat Lodges, I work with the Holy Man in preperations, I fill the pipe for sweats, I am firekeeper at the lodge I built, the ways I follow are Lakota, or Sioux, I have been on Hanblecia or vision quests to the Spirit world. Now I have been called to the Sundance and have commited my self to be pierced and tied to the Sacred tree to Pray for all things on this great Mother Earth. My wife has gone along to this point, but this will freak her out. She says playing cowboys and Indians is stupid. But for those familiar with the culture, This is no Game. How would you tell her.
