When they reached home, they stole in the back way. One of Lois' merry laughs greeted them as they entered.
"Jimmy, you wretch," they heard her cry.
"What's the matter, Lo?" Bob inquired from the door of the drawing-room.
Lois looked up in confusion.
"Jim kissed me under the mistletoe," she said, "after I'd expressly told him not to."
Polly joined in the laugh that followed.
"Bobby," she said as they were taking off their coats in the hall, "I'm ashamed of being such a baby to-day. I acted as if I were eight years old."
Bob pulled a big wadded handkerchief out of one of his pockets. "Don't apologize, Poll," he said. "Look at this. I wasn't so very grown up myself." Then he added, gently, "Good old Sandy."
