如果他们不在那里，留下一张字条，然后再回去。

If they are not there leave a note and go back later.

youdao

如果他们把我的书放在那里，我想，“好吧，这是一种侮辱！有人不想要我的书！”但如果它不在那，我觉得这也是一种侮辱。

If they've got my book there, I think, "Well, this is an insult! Somebody didn't want to keep my book!" But if it's not there, I feel it's an insult too.

youdao

他们已经不在那里了。

They are no longer there.

youdao

It's like they're not smart enough to figure out that it's not there anymore, even if they see it move.

好像他们还不够聪明,不能明白,物体已经不在那里了,即使他们看到物体被拿走了
