Celebrating a language may be important, to encourage more learners.
For me knowing to speak and write English is an opportunity to serve others.
For instance I interpret sometimes during some meetings from French to English. I have new friends all over the world who are English speakers.
When I am in airports travelling to foreign countries I don't need an interpreter. More often those working there speak English. I read books , I listen to news, I do more research in English.
I am privileged to use the most spoken language in the world.
