A high school teacher from Michigan travels to Kazakhstan to teach a class. When the teacher enters the classroom, all the pupils stand up. The teacher is confused and asks a host, who is a native Kazakh, to explain the students' behavior. The host says that students in Kazakhstan get up when a teacher walks in the classroom to show respect to the teacher and remain standing until the teacher tells them to sit down. The teacher thanks the host for a lesson on cultural differences. Which cultural concept does the teacher better understand now?
