I said, "Let's go home together,"
 and you left me behind!
Ich will mit dir nach Hause gehen
und du verschwindest einfach!
¡Te dije que nos fuéramos juntas
y me ignoraste!
¡Te dije que nos fuéramos juntas
y pasaste de mi cara!
Je t’avais demandé de m’attendre,
et tu me poses un lapin !
Ti avevo chiesto di tornare insieme,
Eu te falei: "Vamos pra casa juntas!"
e você me deixou para trás!
Я тебе сказала, пойдём домой
вместе, а ты взяла и ушла одна!
