Haha... This thing about language is so hilarious. It was like that for me when I thought I was already an expert after studying french as a subject in secondary school.
I later got an opportunity to meet some french speaking ivorians. Haha. That was when I realized that the words I learned in school were not enough to communicate with a native speaker.
Funny enough, I'm already forgetting the small french words I know. It's so weird 😂.
