That is hardly consistent
That is inconceivable
That is just like you, if you will forgive me for saying so
That is most fortunate
That is most kind of you
That is most unexpected and distressing
That is not fair--to me
That is not to be lightly spoken of
That is precisely what I mean
That is quite true, theoretically
That is rather a difficult question to answer
That is rather a strange request to make
That is rather awkward
That is really good of you
That is the prevailing idea
That is tragic
That is true and I think you are right
That is very amiable in you
That is very curious
That is very felicitous
That is very gracious
That is what I call intelligent criticism
That is what I meant to tell you
That is a humiliating thought
That is a most interesting idea
That is such a hideous idea
That is the most incredible part of it
That might involve you in life-long self-reproach
That must be exceedingly tiresome
That ought to make you a little lenient
That reassures me
That shows the infirmity of his judgment
That theory isn't tenable
That was exceedingly generous
That was intended ironically
That was very thoughtful of you
That was very well reasoned
That will blast your chances, I am afraid
That will suit me excellently
That would be somewhat serious
That would be very discreditable
The agreement seems to be ideal
The idea is monstrous
The inference is obvious
The notion is rather new to me
The pleasure is certainly not all on your side
The reason is not so far to seek
The same problem has perplexed me
The sentiment is worthy of you
The simplest thing in the world
