Translation of schärfste

Mike, you are very welcome, and thanks for cheering me up. The one thing about the advertisement section on top of the main page is quite right. The difference between your dress and her dress is very difficult to detect, there is only a little change in color.
It is good if you have previously practiced only Spanish, which also shows that you are very good at other languages, and still can learn many things. I hope I'll learn it soon and practice.
I'm glad as well, thanks for the suggestions. I had little time last week as we had many important meetings. I beg your pardon. Let us continue later. Many greetings from Germany.
