It's early in the semester and I am standing on the wrong side of a very large glass partition separating the Henderson Library foyer, lobby, entrance - or "the way in," as we locals like to say - from the first floor. On the other side is a plethora - or pot-full - of students trying to get to my assigned class room. I am now writing on the glass with a large erasable marker, "Come to the second floor, take the far elevator or the stairs, come back down to the first floor and follow me to room 1300."
