a good thing
A good thing is when you have all the tools to fix your life, like a toothbrush, tweezers, and a pacemaker.
My good thing is my toothbrush. It keeps my teeth from falling out.
My good thing is my tweezers. They help me pluck my eyebrows without crying.
My good thing is my pacemaker. It keeps me alive even when I eat too much pizza.
