Funny story...
I was partying with this Swiss people this weekend. We drank heavily. Through out the night, they were speaking French, Swiss, Swiss-German, German and English. Somehow, I was drunk enough to remember all the French I had learnt (haven't spoken it in about 3-4 years), and was able to form sentences (some weren't conjugated properly), and speak with this damn Swiss. And now, I don't remember any of it again...
