“No, papa, I’m perfectly well; but I just want you, as a special favour, to let me stay home to-morrow. And another part of the favour is that neither you nor Grandma shall ask why.”

“Why, of course, my dear, if you really want to stay home to-morrow you may. And I promise you that Grandma and myself will never seek to fathom the deep and dark mystery of it all.”

“Good for you, papa, you’re a trump! Perhaps some time I’ll tell you all about it, and perhaps I won’t.”

So on Friday Patty stayed at home.

She busied herself with numberless little occupations, but somehow her plan, now that it was in operation, did not seem quite so attractive as it had done before. She wondered whether, after all, it wasn’t quixotic and ridiculous. But anyway, the deed was done now, and she must abide by it. Patty never cried over spilt milk, and having committed herself to her course, she dismissed all doubts from her mind. To strengthen her purpose she took her Theme from her desk and read it over. It was good; and without a doubt she would have been marked very high for it. Her spirits rose as she realised that even though Lorraine’s Theme might not be marked as high, yet whatever its marking, Lorraine would stand that much ahead in her average.

Grandma, though mystified at Patty’s remaining at home, said nothing whatever on the subject, and the morning passed pleasantly away. Grandma asked Patty if she would like to go out with her after luncheon and do a little shopping, and Patty readily acquiesced.

After they were seated at the luncheon table Patty looked across the room to where the Hamiltons usually sat, and there, to her amazement, sat Mrs. Hamilton and Lorraine.

Patty’s face showed such a bewildered expression that Grandma turned to follow her glance; “Why,” she exclaimed, “Lorraine has also stayed home from school to-day. Did you know she was going to?”

“I certainly did not,” said Patty emphatically, and then the funny side of the situation struck her and she began to laugh.

At the same time, Lorraine caught sight of Patty, and she, too, looked utterly blank with consternation and dismay, and then she, too, laughed.
