I just read a funny account of a plumber fixing the sink during a lesson over at Yearn to Learn. I could relate to her experience. For some reason this year, I have been plagued with interruptions.
A few months ago, my classroom projector was dimming and yellowing the images I was showing with the document camera. Our technology person said that the bulb was going out, but that it was district policy to wait until the bulb was completely out before it could be replaced. Um...okay.
The next day the bulb went out -- with a loud pop and sparks in the middle of a lesson. It took a long time to get my students back on task.
