I know that in these times of crisis we are among the lucky few that are doing well, and I know that the situation can crash all of a sudden, but as long as it lasts, it's fine

Lo so che in questi tempi di crisi siamo tra i pochi fortunati a passarcela bene e la situazione può precipitare da un momento all'altro, ma finché dura, dura

We don't know why our little fashion business is having, all of a sudden, such a great success, but as long as it lasts, it's fine with us: we can make a lot of money out of it

Non sappiamo come mai la nostra piccola azienda di moda stia avendo, così all'improvviso, tanto successo, ma finché va, va e vorremmo ricavarne più denaro possibile
