It has never occurred to me
It is a curious fact
It is a great pleasure to meet you
It is a huge undertaking
It is a most unfortunate affair
It is a perfectly plain proposition
It is a rather melancholy thought
It is a truth universally acknowledged
It is all very inexcusable
It is all very well for you to be philosophical
It is altogether probable
It is an admirable way of putting it
It is an error of taste
It is an extreme case, but the principle is sound
It is an ingenious theory
It is an uncommonly fine description
It is extremely interesting, I can a.s.sure you
It is for you to decide
It is historically true
It is I who should ask forgiveness
It is incredible!
It is indeed generous of you to suggest it
It is inexplicable
It is interesting, as a theory
It is literally impossible
It is merely a mood
It is most unfortunate
It is my deliberately formed opinion
It is my opinion you are too conscientious
It is nevertheless true
It is not a matter of the slightest consequence
It is not always fair to judge by appearances
It is not so unreasonable as you think
It is often very misleading
It is one of the grave problems of the day
It is only a fancy of mine
It is perfectly defensible
It is perfectly trite
It is permissible to gratify such an impulse
It is possible, but I rather doubt it
It is quite an easy matter
It is quite conceivable
It is quite too absurd
It is rather startling
It is really impressive
It is really most callous of you to laugh
It is sheer madness
It is sickening and so insufferably arrogant
It is simply a coincidence
It is the most incomprehensible thing in the world
