This is risky. Last week I told somebody that I didn't particularly want to see that I would be away on the mainland for a few days. I live in a smallish village on a smallish island and there was a very good chance that he would bump into me again when I was away.
So I had to become a recluse for two days. It developed into a Father Ted like farce where each silly lie begets another lie and I found myself checking the airport timetables for my phantom return flight, and slipping out to the shop at last knockings for supplies wearing what would pass for been on the mainland clothes.
I think I've pulled it off but the hills have eyes around here.
Just say no. Don't want to come. Keep it simple.
