When you don't know what's going on,
 it's best to run!
،عندما لا تعلمين ما الذي يجري
!فمن الأفضل أن تهربي
Wenn man nicht weiß, was Sache ist,
bringt man sich erst mal in Sicherheit.
Si no sabes lo que es, es mejor huir.
Si no sabes lo que es, es mejor huir.
Et quand on a un doute,
il faut fuir !
Quando non sai cosa sta succedendo,
è meglio scappare!
Quando você não sabe o que está
acontecendo, é melhor fugir!
Когда не знаешь, что происходит, 
лучше сваливать!
