I have to tell you this story:
Last Friday I cut Jr's hair. It turned out pretty ok. Hubby decided that he wanted his hair cut too. Monday night I got out the clippers. He said, "I use the #3 normally" I said, "number 3 right?" "yes" so I started the clippers and shaved right down the middle of his head. He said, "no they use the number three in the back!!!!!!" I informed him that it was a little late to tell me that. Hubby now has a burr. We both laughed really hard. I told him that would teach him to ask me to do his hair next time.
