“Are you sure?” said Tom.

“After we had shared so many thoughts, don’t you see?”

“You must be capable of deep friendship,” Cornelia thought aloud.

Tom was somehow crossed by her remark. He lay back once more, brooding. The talk was easy now between the other two. So easy that even silence did not disquiet them. Tom seemed far away.

Out of a silence, David asked: “Is that sort of friendship rare?”

Cornelia, not knowing, did not answer.

“If it is rare,” said Tom, “there must be something wrong with it.”

“What do you mean?”

“The good things in the world are common. Sunlight: moonlight.”

“Mother and I were that sort of friends,” said David.
