I read a disparaging comment a while ago which described Edinburgh as a small town containing 500 people who all know each other. It is sad but true and one of the things I do miss about London is the anonymity you can create.
When I was buying some books for the new course in Waterstone’s, I got chatting with the chap who was helping me find the books because I had left the reading list at home (on my bed…really must start making my bed) and could only remember first names and half titles. Turns out one of his really good friends is also on the part time course! It is indeed a small world and then there is Edinburgh.
