I need a hobby. if you have any suggestions, please tell me. Thank-you.

Hello, I am the riddlemaster. You give me a riddle, I will figure it out. if I give you a riddle, you better figure it out, or live the rest of your life not knowing what the answer is. I know that is cruel and unusual punishment, but that's just how I am. I enjoy confusing people, so if you are going to talk to me. You might just be confused ;)
