“Yvan. […] Que veux-tu que je fasse ? J’ai fait le con jusqu’à quarante ans, ah bien sûr je t’amusais, j’amusais beaucoup mes amis avec mes conneries, mais le soir qui est seul comme un rat ? Qui rentre tout seul dans sa tanière le soir ?” — Yvan. […] What do you want me to do? I messed around till I was forty; oh, I made you laugh, of course, I made my friends laugh a lot with the stupid things I did, but at the end of the day, who winds up alone like a rat? Who goes back to his lair alone at night?
Inherited from Middle French taisnere, tesniere, derived from Old French taisson (“badger”), from Late Latin taxōnem, itself of Germanic origin, from Proto-Germanic *þahsuz (compare German Dachs (“badger”)).
