Read this excerpt from "the medicine bag.” all i could do was stand there with the whole neighborhood watching and shake the hand of the leather-brown old man. i saw how his gray hair straggled from under his big black hat, which had a drooping feather in its crown. his rumpled black suit hung like a sack over his stooped frame. as he shook my hand, his coat fell open to expose a bright red satin shirt with a beaded bolo tie under the collar. his get-up wasn’t out of place on the reservation, but it sure was here, and i wanted to sink right through the pavement. which is a symbol of the grandpa's heritage in this excerpt?
