My mother insisted that no good hostess seated 13 people at a table, not because she herself was superstitious about it, but because a visitor might be. I remember her on one occasion where someone dropped out, scrambling around to find a friend of one of us children who could come to that lunch!
Yes, the supersition is said to be because there were commonly supposed to have been thirteen at the last supper.
So in my book being superstitious about 13 only applies to people eating together.
I would not bother me to live in no. 13, or to make appointments on Friday the 13th either.

This made me quite teary - but smile too
