I've always found English to be odd and ambiguous here (how do you know 
whether "they wash their hands" means: "they wash each other's hands", 
"each one washes his own hands", "each one washes a single hand of his", 
etc...?) French behaves like Spanish, and I have always trouble with the 
English behaviour here.
