I do indeed believe that there is such a thing as superstitions and that some people believe in them. Oh. Wait. You wanted me to answer whether I have any superstitions myself? Then, why not ask that? I suppose that this question *could* be interpreted in that way but the word "any" made itself invisible when I read and re-read it. Do I believe in any particular superstitions? Not any more. Most of my magical thinking and similar delusion stopped about ten years ago and the last few vestiges of such disappeared a couple of years ago. Now, if I can see or otherwise sense it I believe in it. I do not have the time or spoons to second guess the maybes and might bes.
The question I answered here, in case they change it (which they have done before), was, "Do you believe in any superstitions?"
