"My wife and I have naturally simple tastes, and we used to play bagatelle in the evening. When the new servant saw us at it she could not help smiling, and then we were ashamed." -- James Matthew Barrie, 'An auld licht manse, and other sketches'
Bagatelle derives from Italian bagattella, "a trifling matter; a bagatelle," perhaps ultimately from Latin baca, "a berry."
