Once upon a time, there was a big mop. The mop had a special job. It could unlock doors. It was very patient and waited for its turn to help.
One day, a little girl named Sue needed the mop's help. She was locked out of her house. Sue asked the mop, "Can you help me unlock my door?" The mop nodded and went to work. It unlocked the door, and Sue was very happy.
But when Sue went inside, she found another mop! This mop was not patient. It was running around making a mess. Sue and the big mop worked together to clean up. The big mop taught the little mop to be patient. Now, both mops were friends and helped Sue keep her house clean.
