Hello,
Jochen ...
(And BTW "doofus" seems to be a funny word, never heard. It just catched my attention because in German the adjective "doof" exists which is translated by my dictionary to "stupid" or more seldom "boring" ... )
The meaning is the same in English ...
(We probably "borrowed" the word from the Germans.) ...
BTW, Susan just returned from Fort Lauderdale with a wonderful Deutsche Post package from you. Vielen Dank, mein Freund! ...
...
...
Everything arrived in perfect condition.
All the best,
Richard
