I walk away with pens because I am a space head. I don't swipe anything on purpose. I leave school and I have other people's books in my bag half the time. I am not really glued to objects very well. They come with me or are left behind quite frequently. I have to go back in my house at least 3 times before I venture from my door, because I leave things I need behind like clockwork. Yesterday, I left my clock. I needed that and even left the damn clock.
I don't swipe them from banks or other buildings, but I do pick them up when I find them in the street. I have dozens of pens that people have thrown away, and they still write. I have thought about giving some of them away, especially to places where others have swiped them.
I don't think they give them away like they used to. I seem to have a credit union pen in my car. I felt a little guilty when I saw it, but it is a very good writing pen so I made the difficult decision of keeping it in the console. I thought I could return it in the night deposit when it runs dry.
