I was so tired today that walking to class I just started walking into every building I saw. I just decided “hey, I’ve got class in a building. that’s a building. maybe it’s the right one. good enough for me.”
So I walked into one building and desperately tried to find the 2nd floor. Disenheartened by the lack of a 2nd floor I left and went to the next building. It had a 2nd floor but no room 268.
The third building had a room 268! But, sadly, there were no circuits so I left.
Finally I made it to the right building, right room, and somehow I still managed to be on time.
