I know what you mean. I'd rather not bump into an old classmate personally. My mum has and these people started asking her what am I studying, where am I studying at and a load of other things I don't wish to tell. Fortunately I haven't met one of them for about three years.

Consider yourself rather lucky since you don't have it as bad as I do as a fair portion of them not only live in my local community but know where I live.
