It's the last summer of high school.
.إنّه الصّيف الأخير في المرحلة الثّانويّة
Der letzte Sommer
in der Schulzeit.
El último verano de preparatoria
no se repetirá, ¿verdad?
El último verano de instituto
 es irrepetible, ¿verdad?
C’est ton dernier été de lycéen.
L'ultima estate da liceale...
"É o nosso último verão 
no ensino médio."
Последнее лето в школе.
