O
Obviously the matter is settled
Of course, but that again isn't the point
Of course I am delighted
Of course I don't want to press you against your will
Of course you will do what you think best
Oh, certainly, if you wish it
Oh, do not form an erroneous impression
Oh, I appreciate that in you!
Oh, that's mere quibbling
Oh, that's splendid of you!
Oh, that was a manner of speaking
Oh, yes, I quite admit that
Oh, yes, you may take that for granted
Oh, you are very bitter
Oh, you may be as scornful as you like
On the contrary, I agree with you thoroughly
On the face of it, it sounds reasonable
One assumption you make I should like to contest
One has no choice to endure it
One must be indulgent under the circumstances
One thing I beg of you
