If you're always cold, you'll 
lose the fish on your line.
إن بقيتِ باردة دوماً، ستفقدين
السّمكة التي علقت في سنّارتكِ
Wenn du ihm nur die kalte Schulter zeigst,
hüpft jeder Fisch wieder vom Haken.
Si eres fría todo el tiempo,
se te escapará la presa.
Si eres fría todo el tiempo,
se te escapará la presa.
Si tu restes sans rien faire,
ta prise va s’échapper !
Se sei sempre fredda, ti farai scappare il pesce dall'amo!
Se você for sempre tsuntsun,
o peixe vai fugir da rede!
Если будешь равнодушной,
рыбка уплывёт.
