My sister likes swimming。She always goes swimming in summer。But last summer she was very unlucky。
She put her clothes in an old locker。It was hard to lock it。Then she went to swimming。And she Played happily in the swimming pool。Two hours later，she went out the water and took out the key to the locker。But soon she found she can't open it at all。She spent about half an hour to open it but nothing happened。Of course she couldn't wear a swimming suit and go out。She was worry about it。
At last she was angry。She kicked the locker。And it opened!
