"I don't like to put you to trouble," she explained nervously. "I want to sell my piano."

"Yes?" said Thomasina. Was poor little Mrs. Bent in financial difficulties? It would be a great pity if Eleanor had to discontinue her lessons. "That is, not exactly to sell it, but to change it."

"Yes," said Thomasina, who never interrupted or tried to complete the sentences of other persons.

"For a better one."

"Yes." Thomasina saw that her guess was wrong.

"But I don't know much about—about such things." Mrs. Bent had meant to say about pianos, but she suddenly could not remember whether the i was long or short. She knew that one or the other was very wrong, but she could not remember which she had used a moment ago.

"I'll be very glad to help you."

Mrs. Bent's relief showed on her face and she breathed a long sigh.

"What kind of piano do you want, Mrs. Bent?"

"A large one," answered Mrs. Bent, knowing now certainly that she had the wrong word.
