Humor is so culturally based that when I try to tell a joke as me being a white American, if I tell other white Americans, they'll laugh. If I tell an African American, they might not laugh. In fact, they either might not find it funny, or they might find it offensive, and I didn't mean it to be offensive. So these are the sort of little things that build up over time, just like in a marriage. You know, the little things can build up over time.
