"Oh, only how unlike you and Henry are," she replied sweetly.

However, Frank understood something of her hidden meaning, for he flushed.

"Well, considering the fact that you didn't find it possible to continue to live with 'Henry,' I suppose I ought to be flattered. Only as a matter of fact, Frieda, I admire Professor Russell very much."

This time Frieda flushed, realizing that Frank had scored.

"Yet even though that is true, Frank, Henry never took the tone with me of insisting that he was always right and I was always in the wrong. Do you know, Frank, I am beginning to think—oh well, Henry was never so horrid to me as you are to Jack. He isn't a bit of a bully."

"So you think I am 'horrid' to Jack and a bully besides, do you, Frieda?" Frank returned grimly. He was angry, but not as angry as he felt he had the right to be. Somehow he could not manage to get into a violent state of mind with his youthful sister-in-law.

Frieda nodded energetically in response, without appearing the least bit frightened.

"Of course you are going to think I am interfering, Frank, and no one ever pays any real attention to what I say, but I just thought I'd tell you anyhow. You are making a big mistake. Of course I realize that you are not so silly as not to appreciate Jack, but I don't believe you have ever thought what it might mean to lose her. You see she isn't like most women, she really does not know how to quarrel for any length of time. But when she was hurt or seriously angry as a girl she used to keep still for a long time not saying a word. Then she used to do something unexpected." Frieda's voice shook a little with stronger feeling than she often showed.

"I've been afraid lately that Jack might do something queer now, something no one of us dreams she would think of doing. She is so very unhappy. You remember, Frank, don't you, what a long time it took you to win Jack? I wonder if it might not take you even longer to win her back again!"

Frank stiffened. "I cannot discuss my relations with Jack, even with you, Frieda. That is a matter between us alone."
