Where is a Pen and Paper?

Last night I was lying awake, as I often do, cause my brain wouldn't shut off and I kept thinking of things that I needed to do or get. Then I started thinking of my Dad and how he has a pen and note cards tied to a string beside his bed so that when he thinks of something at night he can write it down. I think that he is wise for this because as I said that is often the case with me and I never have anything to write it down on. And almost never get out of bed to go find one. So unfortunately a lot of ideas and things I need to do are forgotten.
