Being multilingual is good, but if you smack talk or talk in code, at least you should know others might understand you!

Just went to the city with coworkers and took the wrong connecting train, and I ended up next to a couple of European tourists.

We took the train to avoid the rain.

I stood next to them, not heavily sweating, wearing deodorant or maybe not a fan or slightly hairy arm. They were talking and got a bit silent. I minded my business but they looked at me once or twice and kept on talking. The train wasn't that rough, and one of them bumped into me, looked at me, giggled a bit, and started rambling with each other.

Among us, we speak a couple of languages, and one of my coworkers understood a good amount and said something, and they quickly got off at the next stop.
