“Don’t cry, Sister!” Sometimes he called her that instead of Sue.

“I—­I’m not going to cry,” Sue answered, but, even then, there were tears in her eyes.  “I’m not going to cry, but oh, Bunny, we’re locked in, and there’s nobody here——­”

“I’m here!” said Bunny quickly.

“Yes, of course,” answered Sue.  “But you can’t get the doors open, Bunny, and we can’t get out when the doors are shut.”

Bunny thought for a moment.  What Sue said was very true.  One could not go through a locked door.

“If we were only fairies now,” said Bunny slowly, “it would be all right.”

“How would it be?” Sue asked, opening her eyes wide.

“Why, if we were fairies,” Bunny explained, “all we would have to do would be to change ourselves into smoke and we could float right out through the keyhole.”

“Oh, but I wouldn’t like to be smoke!” cried Sue.  “That wouldn’t be any fun.  Why we couldn’t play tag, or eat ice cream cones or—­or anything.  And the wind would blow us all away, if we were smoke.”

“Oh, we wouldn’t be smoke all the while,” Bunny said.  “Only just while we were going through the keyhole.  Once we were on the other side we could change back into our own selves again.”

“Oh, that would be all right,” Sue said.  She went up close to the keyhole of the front door and peeped through.  Maybe she was trying to wish herself small enough to crawl out of the locked, empty house, without changing into smoke.

But of course Bunny and Sue were not fairies, and of course they could not turn into smoke, so there they had to stay, locked in.

“But, Bunny, what are we going to do?” asked Sue, as they went back and forth from the front to the back door.

“Maybe I can open a window,” Bunny said.  But he was not tall enough to reach more than past the window sill.  The middle of the sash was far away, and he could see that the catch was on.  If there had been a chair in the house, perhaps Bunny might have stood on it and opened a window, but there was none.

In one of the rooms Bunny did find an empty box.  Moving this up to the window to stand on he found he could reach the middle of the sash, and turn the fastener.

“Now if I can only push up the window, Sue!” he cried.

“I’ll help you,” the little girl said.  “Here’s a stick, I can push with that.”

So with Bunny standing on the box, and Sue, on the floor, pushing with the stick, they tried to put up the window in order to get out of the empty house.

But the window would not go up, and all of a sudden Sue’s stick slipped and banged against the glass.

“Oh!  Look out!” cried Bunny.  “You nearly broke it.”

“I didn’t mean to.”

“No.  But I guess we’d better not try to raise the window.  We might break the glass.”

Bunny knew a boy who, when playing ball, broke a window, and he had to save up all his pennies for a month to pay for the new glass.  Bunny did not want to do that.
