"The tips of my toes are cold
and I can't seem to get any sleep."
"أطراف أصابعي باردة وأعجز عن النوم"
Eure Zehen sind ganz kalt und
ihr könnt kaum mehr schlafen …
¿Se les congelan los pies
y no consiguen dormir?
¿Se os congelan los pies
y no conseguís dormir?
que j’ai les pieds gelés
et que je n’arrive pas à dormir.
Ho sempre i piedi così freddi 
che quasi non riesco a dormire!
"A ponta dos meus pés ficam 
gelados e não consigo dormir."
