What does “cascare dal pero” mean? Literally, “to fall out of the pear tree”: to be, or pretend to be, completely astonished by something that was obvious or well known to everyone else. English gets close with “to act as if you’d fallen from the moon” or the dry “don’t act so surprised”.

You will mostly hear it with a hint of reproach: ma da che pero sei cascato? How could you possibly not know this? It also covers the moment someone finally realises a truth the whole room had already accepted. Informal register, everyday conversation.

The image is rural Italy at its best: someone daydreaming up in a pear tree who suddenly crashes back down to earth, dazed, blinking, out of touch with what everyone below already knew.
