Translation of Kurzschluss

This is a sentence that completes the document so that it will not be shorter than one thousand words. I will add also another one in the second set of words. However, try to learn Spanish or to learn German.
I have sent you the translation a few hours ago. I guess it has just arrived. That is very responsible of you. I will have a look at it immediately. If you want to address somebody formally in the singular, you must use 'usted'.
Have you ever done something like that in Spanish? I also think that we should see each other when you're close, I can help you with Spanish, and you can do the same for me in English. Do we have a deal?
