"Ted!" she exclaimed. "It's a pleasure to meet you, sir! I'm so sorry -- I don't mean to keep you." And as she was talking, she was sifting through the basket on her arm. She found another pear and held it, palm-flat, under the big velvety snout of The Horse. When she looked back at Ted, she was beaming.
"I'm sorry -- I don't mean to be rude. Of course, I won't keep you or your lovely horse! May I trouble you to let Mssr. Crews know that I came?"
