I sincerely hope that this is one of those times.

"I sincerely hope that this time you will give me the right number."

"I sincerely hope this is the last one you'll have to do for a long time."

We sincerely hope that all of you will have a good time.

I sincerely hope this has not reached you too late.

I sincerely hope it has done the same for you.

I sincerely hope that no more lives will be lost.

I sincerely hope that similar decisions will not have to be made often.

At any rate, I sincerely hope this is the case.

I do love these books and sincerely hope you will, too!
