Well, as you can see by my typos in my comment, my typing is indeed terrible and I better proof read (obviously not done in my last comment!). As regards the unicorn: I didn't know that this is a compliment (thank you so much!), I was of the obviously erroneous opinion that a unicorn is kind of a dreaming person not able to be really present in the here and now and have common sense (that includes making sense in a comment). To have common sense is one of the most important things for me, and in this respect you may be right with your remarks regarding my person - there is an enormous lack of it in our present world. I thank you for chatting with me, it is a real pleasure, because you seem to be one of those rare persons, too.
