What happened at the meeting yesterday?
He happened to call while I was busy.
We happened to choose the same hotel.
She happened to find my lost notebook.
They happened to hear the announcement.
She happened to find my keys by chance.
I happened to see your message just now.
He happened to be there at the right time.
I happened to meet an old friend on the bus.
She’s unlikely to cancel unless something urgent happens.
No matter what happens, does anybody really care to help the poor?
