Let alone to talk - as I regret to inform you your nephew did - of love!
"I regret to inform you that the Americans have killed him, as well."
"I regret to inform you that such is not the case."
But I regret to inform you that you're getting ahead of yourself.
Your services as a citizen, we regret to inform you, are no longer required.
We regret to inform you that there is no public parking space.
"Your morning, I regret to inform you, is long gone."
However, I regret to inform you that many of them could not pass our admissions test.
"I regret to inform you that she is all mine now."
I regret to inform you that your husband is dead.
