Translation of Kästchen

On one hand I detest the topics that the media chooses on the news, for example the coverage of the entire trial of O.J. Simpson. But not only this trial, also other completely unimportant events.
Sunday is fine. Please let us talk tomorrow to arrange a schedule of that day. I will call you tomorrow, but in any case, here is my number again. We could do it also on Monday next week, if it fits everybody.
Is there a way that I could test your Spanish and German lessons? Quality is very important to me. Can you send me a lesson electronically (by email or word)? Maybe you have your lesson ready.
