Don't call my name if you're 
just going to clam up afterward.
لا تناديني باسمي إن كنت
.ستصمتين بعدها فحسب
Wenn du nichts zu sagen hast,
sprich mich gar nicht erst an.
No me llames si te vas a quedar callada.
No me llames si te vas a quedar callada.
Me parle pas,
si c’est pour rien dire.
Se poi te ne stai zitta,
fai a meno di chiamarmi.
Se só vai ficar calada, nem me chama.
Не знаешь, что сказать — молчи.
