Two more French sayings:
Autant de têtes, autant d’avis :
Literally: As many heads as opinions:
Too many cooks spoil the broth
On est tous dans le même bain :
Literally: We’re all in the same bath:
We’re all in the same boat
Note: the s in the ‘tous’ in this last saying is sounded, as one could describe it as ‘standalone’. The s in ‘tous’ is not sounded when it qualifies eg ‘tous les amis’.
