Teaching Geometry Class

Night of: Feb. 3
People Involved: ?

I'm in school and it's my turn to walk the class through a geometry problem. It doesn't start great--I draw the problem (a circle) on the white board, but draw it too small and on the bottom, so I rewrite it in the center and bigger. I then drop the black marker I'm using and can't find it on the ground. I pick up another--one with a black cap, but yellow marker. It barely shows up. I try red, but it, too, is hard to see. The class is getting frustrated. One girl with curly brown hair actually speaks out about how I'm taking too long. I respond to her and the rest of the class by saying that I'm sorry I'm not a good teacher, and we're probably doing exercises like these to get better at teaching. When I'm done talking, I notice no one's even paying attention.
I finally find the marker, but write the problem with the wrong information. I correct it and start solving the problem without knowing what it is I'm trying to solve for. After what seems an eternity, I ask someone in the front what the question is asking for, and he says it's the area of the circle. I had already been given the radius, so this was the easiest question ever, but I had turned it into what seemed a 15-minute problem. The good news is that I wasn't nervous being up there.
I quickly put 225pi up. I see that a red marker is attached to my key chain, so I unhook it, and then walk around the classroom to avoid walking straight by students. I make up an excuse that I need to go to the trashcan to throw away stuff. I empty my back pockets, which contain papers from blockbuster (I guess I worked there). I think Blockbuster has something to do with me being dumber than usual.

In Retrospect: I woke up very frustrated and depressed; this dream really affected my mood, and I'm glad I remembered it, because I was able to pinpoint why I felt so crappy, and change that by reassuring myself that it was all a dream.
The problem that I remember drawing on the board was a circle with diameter of 3, and radius of 3 (which makes no sense). Then it changed to diameter of 30 and radius of 3 (still makes no sense, but when I solved it, I actually picked the diameter, and solved it correctly: 1/2 of 30 = 15. 15 squared = 225, so Area = 225 pi). I also remember writing 7pi/4pi, but I don't remember how that came up.
