I'm with those who say best to ignore.
I've never forgotten a couple of phone calls I had a few years ago from a male voice, asking how many aprons I had. I played him along a bit and he asked what colour, long or short etc. Then made a few comments which indicated that he knew me, which was creepy. Never heard from him again.
I made some enquiries and another lady I know had a similar call. So it seemed to be in our community, I had my suspicions who it was.
There are some weird people about who get their kicks from doing things like this.
