You needn't say any more at any time.

I decided the day I saw you walking into that vestibule that you were an exceptional man; now I know it.
You needn't apologize to me.

I haven't lived in this world fifty years and more without having my eye-teeth cut.

You're welcome to the courtesies of this bank and of my house as long as you care to avail yourself of them.

We'll cut our cloth as circumstances dictate in the future.
