I wanted to share a quick story, but it's intention is not to excuse bad behavior. I speak two languages very well. One of the languages is relatively uncommon and I have only ever heard it spoken by native speakers. Recently I was at an event and am American told me they learned this language. I'm like that's cool as hell, let's hear. What came out of their mouth shorted out my brain and my brain refused to answer them in anything other than English.

I have no rational explanation of what occurred inside of my head. My partner actually asked me why I didn't respond back in the same language and I had no answer.
