I never thought to ask her where she was going.

But I never thought to ask why he isn't here.

And my kids would never think to ask him to make something.

No one would ever think to ask him what he wanted.

Everything happened so quickly, and I never thought to ask.

But I didn't think to ask him where he was.

I couldn't think of anything else to ask or say.

I don't believe either of us thought to ask which.

She couldn't think quickly enough to ask the right questions.

But I could not think of anything to ask for.
