You're going to bump into someone, 
fall down the stairs,
ستصطدمُ بشخص ومن ثمّ
توقعه في الدرج
Sie rennen noch in jemanden,
fallen die Treppe runter …
Va a chocar con alguien, 
caer por las escaleras
Va a chocar con alguien, 
caer por las escaleras
Vous allez bousculer quelqu’un,
Rischia di scontrarsi con qualcuno, 
finire giù per le scale,
Vai acabar trombando em alguém,
 empurrando-o escada abaixo,
