Translation of sidekick in Spanish

Thank you for writting back so quickly. I learned English when I was a kid, because we've always been in England during summer vacation, since my grandma used to live there when she was still alive.
The words will mostly be easy. I would prefer full sentences and not just short clauses with the article, the noun and an adverb/adjective. Do you think you could do 1000 sentences per working day? This way we could finish quickly.
I would be glad if you can tell me more about the United States, of course in German! Maybe we can talk again when you're back at home, what do you think? That would be a good practice, wouldn't it.
