I cut my own bangs once when I was about five. I asked my mother to do it and she told me to wait one minute. I waited about one minute and then became impatient and decided it couldn't be that hard. Well, I ended up having to get them completely cut off since I cut them at a 45 degree angle.
I once decided to have my friend cut my hair to save money since I was donating ten inches to Locks of Love. They totally butchered my hair and I had to pay to get it cut anyways to straighten up the mess.
You didn't do too bad of a job yourself, though!
