It was a cold day, and Ali stared at the white snow that covered the sidewalk. He knew he had a lot of shoveling to do. He was supposed to clean off the whole sidewalk. Out in the street, Ali's friends were pulling their sleds. Ali knew they were going to have fun sledding down the hill. They called for him to come, but Ali just waved. As they walked away, Ali slowly started to shovel. What can you infer about Ali?
When Ali has a job to do, he does it.
