Lost Shoe<br>It was time for Ingrid to go to school. She had one shoe on. She couldn't find the other one. She finally found it under the couch. Dressed at last, Ingrid walked to school.
Ingrid needed her shoe to go to school.
While a shoe would make going to school easier it isn't something needed.
