When my parents lay in their own bed, I'm going to cut off their hair.
Why would you want to do such a thing?
My parents need to learn that it's not okay to try and control my life. This way they will learn to mess with me too much.
I find it fair to be upset that your parents are so controlling, but it's not a good idea to get back at them because it will only make things worse. It would fare better to tell them how you feel, so put away the scissors.
I don't care. I'm a psychopath.
If there is something wrong with you then you should get help. Being a psychopath is not normal. You need to be treated before you hurt your parents.
