The problem with living in a polyglot household is sometimes you don't know what things are called in your native tongue. Well, that is my excuse, it is probably something more serious like ageing. A fine example is I don't know what that thing that people use to clean their terrace is called in English. In Spanish it is called a limpiador de hidropresion, so I call it a power shower. Mr van de Ven has just corrected me. 'It is not a power shower', he says, 'it's a pressure cooker!'
