Once upon a time, there was a modern thermometer. It liked to work very hard. Every day, it told the family how hot or cold it was. The thermometer was very good at its job.
One day, the thermometer met a little girl named Sally. Sally did not know how to read the thermometer. The thermometer wanted to help Sally. So, it showed her how to see if it was hot or cold. Sally was very happy.
From that day on, Sally and the thermometer were best friends. They spent all their time together. Sally learned more about hot and cold from her friend, the modern thermometer. They were very happy and had lots of fun.
