In 2016, 5-year-old Walt from San Francisco saw an ad for a campaign. Its goal was to collect pajamas and give them to families with adopted children. This ad impressed Walt so much that he asked all his friends and relatives to give him only pajamas, which he later gave to adopted children. A little time later, Walt and his mother set up a foundation, and in less than a month they raised more than $4,000. Walt realized that homeless people also need help. So he and his sister became volunteers in a local nonprofit organization that helps homeless people and low-income families.
