I don't understand the following sentence from my textbook:
学校を休んで遊んでいるところを友達のお母さんに見られた。
I think this sentence means
Mom saw us while we were playing hooky from school.
I don't understand why を is used after ところ instead of に, で, or が. I think を marks the direct object, 学校を休んで遊んでいるところ, of 見られた. I don't understand why the passive verb 見られた would have a direct objet.
- What does this sentence mean?
- Why is ところ followed by を, and what is its meaning?
- If を marks the direct object of 見られた, why does it have a direct object?
