At Schoenbrunn Palace in Vienna:
Entschuldigung, ich habe my sohn verloren. Er hat ein blaue Jacke und ein kleines Pferd.*
* I'm sure that isn't grammatically correct, but I meant to say "Excuse me, I have lost my son. He has on a blue jacket and has a toy horse." Now I realize that I must have said, "Excuse me, I have abandoned my son."
