                             ...pour distinguer l'extérieur d'un  
aquarium,
                                            mieux vaut n'être pas  
poisson

                            ...the ball I threw while playing in the  
park
                                           has not yet reached the  
ground

               Es gab eine Zeit, wo ich nur ungern über Schubert  
sprechen,
            nur Nächtens den Bäumen und Sternen von ihm vorerzählen  
mögen.
