I believe this is exactly the mistake I made.

We’re both white.

This is what I have thought. It’s a guideline we help with learning language by speaking it with clean vocabulary, avoid swearing and use everyday language. I wanted to make an effort to learn the greetings.

Usually she’s a very nice person.

I had so many ways to do it correctly, so I did actually screw this up. Asking her would have been the best option. Showing interest on communicating with her. Instead I was so eager to say it and show what I learned, that I forgot I might have wrong term. It’s gonna keep me humble for a while.

I thought I was being rude before, as I speak with three co-workers in their language(english), but not with her or others from her country as they don’t speak english nor my language. Mostly we communicate with google translate and it’s bad.
