You cannot imagine or believe how small the world is, and how petty and nasty some people with a bee in the bonnet can be. I joined a French Forum about 5 years ago, and got into an argument about a 'society' and what they get up to, and one of the Moderators (a member of said 'society') didn't like it. He knew my first name, the town where I lived in UK and that I was a teacher + subject. He phoned the Headmaster of a school there (member of same said 'society) and asked if he knew of me. He didn't, but asked his Head of Department for my subject, who of course knew me very well, as we met often as I also was head of dpt. Bingo - she also knew my husband and his job. He then made threats to me, saying I should be careful about my family!!! And when we next visited, friends of ours at his sports club asked us why this guy was asking questions about us. Incredible and disgusting- fortunately we have no family there any longer. But it just shows!
