premise: On one occasion I know I would have cut if I 'd have had a razor blade in the house ( other than a disposable one which I tried unsuccessfully to take apart ) . Another day I tried - but the paint scraper razor blade was too dull . I do have safety pins in my house now . That came about 1 month ago when I purchased some used baby clothes at a consignment sale and the sales price was safety pinned to the garment . Why do I cut myself ?
hypothesis: Because I have safety pins in my house now .
