We didn't have to go to school yesterday.
(What is the meaning of the sentence?
Is it #1 or #2?
1. We didn't go to school yesterday because it was useless.
2. We went to school yesterday, but it was useless. )
I don't sense any "useless" idea in that sentence.
The sentence means we didn't go to school yesterday because we weren't required to. Maybe it was a holiday, or maybe the snow was so deep no one could get through! Or something else that meant there wasn't any school yesterday.
