There are two attitudes toward other cultures. Minimization = Hey, deep down we're all the same. Defense = We're different and they're silly and quaint. Encouraging students to actively look for evidence contrary to their attitude deepens their cultural learning.
There is no such thing as common sense. Common sense is really cultural sense.
Behaviors can vary even when beliefs and values line up. Sanitation for example, in the west we use utensils believing it more hygienic than using one's fingers. Other cultures disagree.
Simply awareness is not the goal. It's bridging the gap.
Mish mooshkilla: No problem, no problem. I'll have that for you Friday. Translation: You might get that next Wednesday.
Generalized tendencies: ahem, stereotypes.
Start from a place of positive intent. Other cultures are not failed attempts at being you.
