hubiesen avisado

Si no fuese importante, no nos hubiesen avisado.
If it wasn't important, we wouldn't have come calling.
Era el día de Año Nuevo, cierto, pero si nos hubiesen avisado nos habríamos organizado de forma distinta y nos habríamos quedado hasta más tarde en Manhattan aquella noche.
It was New Year's day, sure, but had we been warned, we would have got organized differently and stayed longer in Manhattan that night.
