I dreamed last night that I was trying to help a college friend buzz, then shave his head. I just could not get the clippers to trim anything. It took so long that my hair grew out to about 1/2 inch. When I tried to buzz my own head down, I was also unable to get the clippers to work and I was stuck with a #4. It was so frustrating. When I woke up, I had a good laugh and was pleased to be SLY again.
