I got my first paid for haircut when I was in high school. I had to pay for it. My Dad cut my hair until then. One year during Football season (November probably) he was cutting my hair in front of the TV. He ran the cutter up over the top of my head accidentally. I got a total buzz cut that time. He left our hair longer in the winter, but still short. And buzzed us in the summer.
I have cut my own hair since the beauticians I used to rent to moved out of my building. I hate having to make appointments as much as I hate $20 for something I can easily do.
