The machine I clean the cafe floor with was sitting in the cafe and Alan loved turning that key and turning it on. There is a few buttons to push as well. I let him push those buttons and he was so proud as he was able to do it. So once after his lunch last year I let him run the machine with me controlling the speed and machine. He got to walk with it as it was running and he was the talk of the 1st graders that he knew how to run that machine.
