Lyric discussion by floodline 

Who will be at Sanssouci tonight? Surely not the one that loves me truly, only He's probably down at the stables, there Gently polishing my cabriolet

Only through the window you can see them Once the door is open, all will vanish

... so the only ones who are real in this song are the singer and his lover? The two of them, avoidance, and too much time in hotel rooms. Ennui kills the best of intentions. And the best of relationships.
