“I guess we’ll have to go buy sodas,” agreed Brother disconsolately.  “Only if I don’t go to movies pretty soon, I’ll—­ I’ll—­I don’t know what I’ll do!”

“I know,” said Sister, dimpling mischievously.  “I’ll tell you, Roddy.”

“You be good, Sister,” warned Ralph, eyeing her a bit anxiously.  “I couldn’t take a naughty little girl to the movies, you know.”

CHAPTER XIV

TWO IN TROUBLE

Ralph knew that Sister could put queer ideas into Brother’s head, and he hoped that the fun of going downtown, and buying ice-cream soda at the drug store, might cause Sister to forget whatever she had in mind.

When he came home from his tennis game he found both children playing in the sandbox, and as they were very good the rest of that afternoon and evening and all day Sunday, Ralph decided that Sister was not going to be naughty or get Brother to help her to do anything she should not.

Monday evening Mother and Daddy Morrison went through the hedge into Dr. Yarrow’s house to visit the doctor and his wife.  Brother and Sister were told to run in and visit Grandmother Hastings until eight o’clock, their bedtime.

“Can we take Brownie?” begged Sister.  “Grandmother says he is the nicest dog!”

So Brownie, who was now three times the size he had been when Ralph brought him home in the basket, was allowed to go calling, too.

“Grandma,” said Sister, when Grandmother Hastings had answered their knock on her screen door, and had hugged and kissed them both.  “Grandma, couldn’t we go to the movies?”

Now Grandmother Hastings was a darling grandmother who loved to do whatever her grandchildren asked of her.  It never entered her dear head that Mother Morrison might not wish Brother and Sister to go to the movies at night.  She only thought how they would enjoy the pictures, and although she disliked going out at night herself, she said that she would take Brother and Sister.

“We can’t go downtown to the Majestic,” she said, “for that is too far for me to walk.  We’ll have to go over to the nice little theatre on Dollmer Avenue.  If we go right away, we can be home early.”

Sister lagged a little behind her grandmother and brother as they started for the theatre.  She was stuffing Brownie into her roomy middy blouse.  He was rather a large puppy to squeeze into such a place, but Sister managed it somehow.  Grandmother Hastings supposed that the dog had been left on the porch.

The theatre was dark, for the pictures were being shown on the screen when they reached it, and Grandmother Hastings had to feel her way down the aisle, Brother and Sister clinging to her skirts.  The electric fans were going, but it was warm and close, and Grandmother wished longingly for her own cool parlor.  But Brother and Sister thought everything about the movie theatre beautiful.
