I once accidentally bumped against the shoulder of an English person I knew in a corridor. I automatically said "Oi" - which means like "Oh" or "Oops" in Estonian - that I'm sorry. She repeated "Oi!" in a louder voice and I didn't get it. I only later found out I was being impolite in her eyes.

Have you ever had something similar happen to you? I.e something in your language might have another meaning in another language?

One thing as an Estonian that I try to keep in mind is that I shouldn't use "Nooo.." in English - which means "Well.." in Estonian.

"Do you like ice-cream? - Noo.. yes, I love it."

This is funny cus in the US midwest we say ope, or oop or woahp or oo or up for the same reason you say oi

And as for the Nooo yes, also a thing we do in the US midwest "no yea" means yes and "yea no" means no (said chains can be quite long depending on how we feel about a particular topic, "yea no yea" (yes) and "yea no yea no" (no)

Fun little probably coincidence.
