What are two problems that Marty and Henry have?

Henry:

The neighborhoods and the many physical barriers are reflective of the invisible, yet strong, cultural barriers that separate many cultures form interacting. While at Rainer Elementary, Henry and Keiko encounter mass discrimination due to the fact that many at Rainer have never encountered a Chinese or a Japanese student.

These barriers prevent harmony. Other barriers, like the fence that separates Keiko and Henry at the internment camp, represent the separation that culture imposes on groups that seek harmony.

Henry and Marty:

Henry and Marty completely disagree about Ethel's care and condition. Henry cares for her lovingly and relentlessly, whereas, Marty feels that she should be put in a home.
