we had a couple different history teachers. the last two years one of the brothers taught American History, (AP and AP Gov't). he was a nice guy, but an awful instructor. I was not prepared for that AP exam at all.
not sure when you were there, but my mom used to work with an older lady who's three kids went to BR well before me. incidentally, they had a history teacher who sounded kinda like that. He was a great teacher and well-liked, but they all told their mom they smoked pot with him on the weekend a couple times. apparently the administration heard rumors, and he was fired. sounds kinda like Dead Poets Society or something.
I have no idea whether any of that was true or not, but it's what I heard.
