Talking to my mom and sister about things that happened in Slovenia is easy and fluent. Talking about things that happened in USA is … hard. I have to translate, I can’t find words, the concepts make no sense, everything is awkward.
Make me talk about software engineering in Slovenian and I sound like a bumbling fool. It just doesn’t work. Every 3rd word is English. Entire sentences sometimes.
[1] I speak Slovenian maybe a couple times per month nowadays
