¡Cada día!

This happens to me with german english and afrikaans

I understood this? Wow, I thought I was flunking German @_@

Try three at the same time. Or mixing Dutch and English words, topping it of with German grammar.

Sometimes this happens when I'm asking some one questions...
Me: Wie spät es ist?
Person: wat
Me: (scheiße, Englisch nicht deutsch!)

Yeah I speak five tongue do you know jow annoying this gets?!

I speak three fluently and understand around six. It can get confusing lol. Also i have this on a shirt but with french instead of german

Me: *is talking*
Mum: Rachel, in English. Nobody else knows Spanish

I do that with English, Spanish, Japanese, and occasionally even in Sign Language (can think of the sign before the word).
