My head throbs because it is raining outside and I want to be putting down lye and grass seed. My head throbs because I want to go back to yesterday morning and do yesterday completely different. My head throbs because I need to be working on my client’s work but I want to be writing. My head throbs because I have not yet had coffee. My head throbs because I want to be cleaning my house and making repairs. My head throbs because I have dreams I cannot, will not ever fill. My head throbs because I want to be doing my taxes. My head throbs because I am thinking about anything except what I am doing.
