Indefinite pronouns for ideas or situations

Hello teachers,
Is the following definition correct, ‘The indefinite pronouns: everything, something, anything, and nothing are used for things, ideas, situations, activities, or information.’?

If it is so, I can think of examples for things, activities, and information.
Examples:
I am starving. I want something to eat. (things)
Our holiday was a disaster. Everything went wrong. (activities)
I don’t know anything about a car accident. (information)

But I can’t think of any examples about ideas or situations.
Please, could you tell me a sentence for each one?

Thanks in advance.

I can think of nothing to say about that.
Can anyone think of anything which would fit that pattern?

Hello Beeesneees,
Thank YOU so much for your help. I really couldn’t find any sentences for them. Now it’s crystal clear.
Then the definition is correct! :slight_smile:
