My boss Blair (born and grew up in Grangemouth) has just offerred definitions of pochle and boufin, using them in connection with an informal attitude to ownership and a strange smell respectively. I'd assumed driech was common parlance (spelling it dreech) until fairly recently.
Those two old ladies, Doris and Cissie, were born and grew up in Glasgow, but eventually lived in Rosyth and Dunfermline respectively. They were two sisters of Anne's late mother. But I'm assured from several quarters that it's an almost universal pattern of behaviour.
And yes, our family has always had copies of the annuals from oor_wullie and the_broons around the place, although we never got the Sunday Post.
