I'm concerned.

I doubt it.

I put the phone on disorder.

I doubt if he is a lawyer.

I always suspect a trick.

I suspect, but I'm not sure.

I don't even suspect anything.

I've never doubted your good taste.

My boy, never for a moment did I doubt your innocence.

I doubt if I paid it quite the same attention as you have.

Gee, I doubt I'll make Max's best people list.

What do you think, Jeeves? I doubt it, sir.

I suspect nobody and everybody. I'm merely trying to get at the truth.

I do know of one... but I doubt if the owner would part with her.

But I also suspect that a fair number of those secretly despise religion as much as I do.

I doubt it.

Right, I don't doubt that for a moment, but we are the last two people that should be near him right now.

I'm beginning to doubt if it was wise to save him. From now on, he'll be insufferable.

I doubt it.

Sometimes I have me doubts about you.

I doubt not of your wisdom.

I doubt it.

I doubt that!

I suspect thee art not a Christian.

I doubt it.

I'd say he is.

I believe he is!

I do not doubt him.

I doubt they will be helpful.

I doubt if anything is to be gained by questioning you any further.

I am skeptical.

I wonder. What do you mean?

Not too greatly, I suspect.

I never doubted you, mademoiselle.

I doubt it.

I doubt that, the population's only 18,000.

I didn't doubt your statement.

I bet you would do that.

I doubt it, senhor.

But I doubt it.

I doubt he'll join us.

I'm not even sure whether he has a heart.

I very greatly doubt it.

I always thought you were innocent.

I would never question his honesty.
