Nowadays, I almost always write in English. I do have a few stories in Spanish that I’ve written years ago, and I even wrote a little in Greek when I was living in Greece during my teenage years.
I only write in English as that’s the only language I’m fluent in.
But I’d like to write in more languages once I know more in the future.
