Until three years ago, 10-year-old Guy Kenny didn’t realize that not all kids get to celebrate Halloween.

But then Guy and his family got an e-mail from the Homeless Children’s Playtime Project, which gives homeless children in the District toys and space to play. The e-mail asked him to donate costumes for the project’s Halloween party — otherwise, the kids wouldn’t be able to dress up.

“It made me so sad,” Guy said. “On this holiday, everyone deserves to have a fun night.”

So Guy and his sisters, 7-year-old twins Maya and Amalia, started collecting costumes at their school, Lafayette Elementary in Northwest Washington. This is their third year collecting for the Homeless Children’s Playtime Project, and they hope to donate more than 400 costumes before Halloween.

“It makes the kids really happy, and that makes me happy,” Amalia said.
