I wrote half an essay in Dovahzul once. Just switched over in the second paragraph, and didn't notice until I was writing my conclusion.

Update: I wrote a 10,000 word essay in dovahzul. And trust me, it wasn't nice. 

Duuuude, this happens to me all the time! I'll be talking in ordinary English fod nol my motmahus tongue meyz Dovahzul. Daar how I think: ko Dovahzul voth osos English where canon doesn't have a rot. The funny thing is that last year, my Spanish class was garbage because the new teacher wasn't effective, nor were the many other subs that replaced her, so I spent the entire first half of school with a printed copy of the 52 page PDF file and studied tol enook sul lingrah morah sinon Spanish. Ful as I was learning Dovahzul, I was hearing Spanish, and so sometimes I fill in blanks in Dovahzul with Spanish, and vice versa.

My sister has learned to respond to "briinah", she knows that when I groan and say bahlok it means I'm hungry, and fod zu'u listen wah others tinvaak, I silently translate it without naan morah. But I didn't write an entire vomindoraan lingrah essay ko Dovahzul. And I thought I was bad. ;)

BoDuSil has this error all the time. BoDuSil was asked a math question in math class, and told teacher to "F*** off" in dovahzul

Really? I tell it in English!

I became fluent in English when I was about eight years old. Ever since I have been switching languages while thinking without noticing all through the day. Sometimes I suddenly realises that I'm thinking in English, or Dovahzul, or heck, Japanese. Speaking is a different thing for me though, perhaps because I put a lot of thought into my words or something, because I always talk in the appropriate language.

I was fluent in three languages by nine, and that was when I became incomprehensible.

I was fluent in three languages by nine, and that was when I became incomprehensible. 

Incomprehensible at 4, brought up with French, English and Swedish.

And it happens all the time to me, not with Dovahzul as such, but it has happened.

Most embarrassing moment would be when I stormed into a room to sort out a massive data loss, and started yelling orders in part Russian and part Norwegian. They s*** themselves.

When I was nine, my speech accelerated at a high rate, I mean to say that, I could (and still can) say 'the quick brown fox jumps over the lazy dog' in two seconds, and that (still is) my regular speech. 

Zu'u think ko Dovahzul almost pah fin tiid ahrk osos tiidde tinvaak nii nau accident. Fod other people tinvaak wah zey, Zu'u translate nii wah dovahzul. Zu'u los rinik pruzah ahst pel ko dovahzul.

Ahnok, lok thuum, guur, krosis. It's embarrassing, huh?

Aalkos.

Actually I think it's kind of funny if people ask me what's wrong with me because I have a weird sense of humor like that. As long as I don't start writing runes on a job application I should be fine.
