Impossible choice

Why French or English? Why not French and Anglais? Ça donne des trucs comme “face de livre” – la tête in the bucket (and yes in that case it’s a bucket with no list on) – sky mon mari (which is incredibly close to “Aie mon mari”… et on sait bien que ce n’est que le début du aie quand le mari arrive…). It seems we often misunderstood multilingualism. Indeed, it’s not about learning to say the same thing in different languages, it’s about expressing something in different languages, and there are things that are perfect in English, and other in French, and any other languages. My brain sees it as its own freedom of expression, et vous?
