"To what?"

"To friskiness. I NEVER know what you're going to do next."

"Isn't it nicer to be surprised?"

"Well,—that depends. It is if they're nice surprises."

"Oh, mine always are! I'm going to surprise you a lot of times this summer. Are you to be here, at Mona's, all the rest of the season?"

"I shall be here two months, anyway."

"That's time enough for a heap of surprises. Just you wait! But,—I say,—I suppose—oh, pshaw, I know this sounds horrid, but I've got to say it. I suppose everything you're invited to, Mona must be also?"

Patty's eyes blazed at what she considered a very rude implication.

"Not necessarily," she said, coldly. "You are quite at liberty to invite whom you choose. Of course, I shall accept no invitations that do not include Mona."

"Quite right, my child, quite right! Just what I was thinking myself."
