It is interesting how dogs learn English. Nicki-the-Lab has always associated "wan' go out?" with what the question suggests and the phrase invariably provokes a ferocious, affirmative happy-dance. I don't even have to say, "out" -- the word "u'wann'?" suffices.
But it has been grim and rainy of late. This evening Nicki came alongside as I lying on the bed and resting my eyes. Tonight, as last night and the day before I sighed, "Ohh, you're such a pain in the butt" and this phrase immediately provoked his happy dance. So we went out.
