text:  This Tuesday, April Davis will change the world. She doesn't know that yet. All she knows is that she went to JustServe.org and volunteered an hour of her time. Browsing through dozens of service opportunities in her community, April decided to spend her Tuesday evening serving dinner to mothers and their children at a transitional house. She doesn't know she'll be serving a particular mother and daughter who will be spending their first night in this home.
