Personally, I drank because I wanted to, not because of any perceptions of being "cool" or "uncool". In the second semester of my senior year my last two blocks were a "study" period followed by History. I frequently spent study block in the parking lot, smoking dope and drinking sweet white wine with a couple of buddies in a VW microbus, and would go to my history class loaded and floating, on the days I didn't cut the class. Got 97.5 percent in the class, and aced the provincial exam, to the distress of the first year out of college punk who taught the class and hated me.
