Translation of expired in German

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.
Somehow, my email was not sent. There were even a few mistakes, but really only minor things, nothing really bad. I've already read some other texts that you have sent and are getting better each time.
First, let me thank you for your answer. And how can I support you further? I'd be very happy about it if we could both help in each other in learning Spanish. 'Tandem' learning beats all other methods.
