Culture
The definition of this word has undergone (and is undergoing) so many changes, that some of us want to throw up our hands and proclaim that everything is culture.  Although I don't agree completely, I am regularly startled by how easy it is to identify something as a product or part of a culture.
Too often we get used to seeing only a couple of aspects of culture, such as the traditional clothing, music, and food of X people.  Although it is certainly important to appreciate these things, and much can be learned from in-depth study of them, there is so much more to culture than just these three.
What about beliefs? What about attitudes? "Common sense"? Oral history? Cosmology? Linguistic cognition? Gender roles? Kinesics and proxemics? 
OK - so I'm getting a little ahead of myself.
So here are two questions to ponder:
1. What aspects of culture get rammed down your throat to the point where you wish you'd never have to encounter them again?
2. What are some aspects of culture that you wish people would pay more attention to?
