We didn't turn in our homework because
They were really nervous of flying
When the waiter finally arrived with the food,
When we found him
Their house was a mess but they were happy because
By the time her favorite T.V show started
When I saw Alice she was tired because
By the time I went over to help her,
she hadn't finished her homework.
they had had an amazing party!
the guests had already left the restaurant.
he had already asked for help.
because they had never traveled by plane before.
she had run all morning
she had almost put all the bags in their place.
we hadn't had time to finish it.
