were passing, passed, were spending (time)
Ho visto che le passavano sopra.
I saw them walk over her.
— La società della neve (2023)
Passavano ore a parlare e a ridere.
They spent hours talking and laughing.
Aveva molte idee che le passavano per la testa.
She had many ideas running through her head.
Non avevo visto che passavano.
I hadn’t seen that they were passing by.
— Il profeta (2009)
