In their defense, my first grade teacher caught me cutting my own bangs (my mom was trying to get them to grow out but they were in my eyes disrupting learning!) I cut them perfectly and you couldn’t tell that I had done it myself. 😀
My son did something like this. He really likes to spike his hair but his hair was getting too long (this was a couple years ago). Unfortunately he didn’t realize you need to have hair in order to spike it! LOL! He cut it so close he barely had any hair left on the top of his head. He had a reverse mohawk! I had to have his head completely shaved.
