blurt

It took Penelope a full minute to recover the power of speech, and when she did, all she could blurt was, “How did you know?”

But instead she blurted, “It appears you have been exercising.”

Simon shoved his hands in his pockets and shifted his weight around a bit, then blurted: “Say, Miss Lumley—do you like to go see shows?”
