Grandpa, who is a Native American elder, comes to visit Martin and his family, and his arrival brings a mix of anticipation and embarrassment for Martin.
Martin feels ashamed of his heritage and worries about how his friends will perceive his grandfather. When Grandpa arrives, he is not dressed in the way Martin expects, which further heightens Martin's anxiety.

Ultimately, the visit becomes a pivotal experience for Martin, as it helps him connect with his heritage and understand the importance of family and the traditions that come with it. The story emphasizes themes of identity, tradition, and the connection between generations.
