A

A most extraordinary idea!

A thousand hopes for your success

Accept my best wishes

All that is conjecture

Allow me to congratulate you

An unfortunate comparison, don't you think?

And even if it were so?

And how am I to thank you?

And in the end, what are you going to make of it?

And yet the explanation does not wholly satisfy me

Apparently I was wrong

Are we wandering from the point?

Are you a trifle—bored?

Are you fully reconciled?

Are you not complicating the question?

Are you prepared to go to that length?

Are you still obdurate? [obdurate = Hardened in wrongdoing; stubbornly impenitent]

As it happens, your conjecture is right

Assuredly I do

At first blush it may seem fantastic
