The beautiful shapes you love the most 
never come back a second time.
.الأشكال التي تحبّينها أكثر لا ترجع مجدّدًا أبدًا
Die schönsten Formen, die man so geliebt hat,
kommen nie mehr zurück.
Las formas más lindas
son las que nunca vuelves a ver.
Las formas más bonitas
son las que nunca vuelves a ver.
Car la plus belle forme
que j’aime le plus
Le belle forme che tanto ti ammaliano
non tornano più.
As belas formas que você mais ama
nunca mais voltam.
Прекрасные картины, которые тебе нравятся
больше всего, никогда не повторяются.
