Clement,

Take it easy, it's a compliment to the answer of my question. I am exploring 
and learning a new language. Your english is much better than mine, but if 
you are more comfortable with your native language, feel free to do so.

Ich lasse mich nicht von Deinen Bemerkungen irritieren, es war nur Fragen 
und Antworten, Du brauchst nicht diese als eine Gelengenheit Deinen Dienst 
fu"r Ruby zu beklamieren.

mfg
Dat
