When Sara and Nathan Jones were training to become foster parents(养父母), their son, Noah, learned a tough thing or two about foster care. For instance, nearly 600 local foster kids changed families every year, and they carried their belongings from one home to the next in black garbage bags.
Noah, then ten, couldn’t imagine squeezing his clothes, favorite toy, and soccer ball into a trash bag and dragging it to a new house in the middle of the night. “Packing kids’ belongings into garbage bags is like telling them that their stuff has no more worth than trash” says Noah.
So with help from his parents and younger sisters, Macy, then nine, and Molly, then seven, Noah began to collect suitcases and duffel bags(行李袋) from friends and extended family； he received more than 100 bags in less than two weeks. He then sent letters to churches and put ads in local newspapers and on radio stations asking for donations. Within a few months, the family was collecting about 500 bags a week, which they stored briefly in their spare bathroom and downstairs hallway before giving them to foster care caseworkers.
