Final answer:
Martin was embarrassed by his grandfather in 'The Medicine Bag' because of the deference his grandfather showed, reflecting an old-world mentality that conflicted with Martin's wishes to fit into the modern world without being seen as different.
Step-by-step explanation:
The question refers to the story The Medicine Bag by Virginia Driving Hawk Sneve, which narrates the feelings of a young boy named Martin who feels embarrassed by his grandfather.
Martin is self-conscious about his Native American heritage and worries about how his friends will perceive the traditional practices and appearances associated with that culture. The statement provided alludes to the theme of the story, which explores generational differences and the internal conflict one might feel between honoring one's heritage and fitting into modern society. Here, the grandfather unknowingly displays deference, hinting at his past and the social hierarchies he has experienced. Martin's embarrassment stems from this old-world modesty that clashes with his desire to assimilate into his present environment and be seen as equal among his peers.
Martin was embarrassed by his grandfather in the medicine bag because his grandfather's behavior reflected a lack of social status and wealth. Martin's grandfather showed deference towards the wealthy and well-born, which made Martin feel self-conscious and embarrassed. This embarrassment manifested in Martin's interactions with others, including his own son, as he unconsciously adopted some of his grandfather's deferential behaviors.
