Translation of weightlessness in German

Hans was not in the office for 4 days. I informed him that it is urgent and asked him to send it by tomorrow morning. I'll do my best that you receive it as early as possible. Trust me on that.
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.
Not worth mentioning. The next day we spent the entire day in the mall buying unuseful things, cheap Jeans of poor quality and again gifts for our friends. I remember buying swimming pants in the sports store.
