Yelitza Castro, an undocumented immigrant who works as a housekeeper in Charlotte, N.C., cooks dinners for homeless men and women every other Saturday night. It's a tradition that started after she and her children spotted a man standing in the rain on a cold day with a sign asking for help.
Yelitza gave the man $5, she recalls, but her children wanted to take him out to dinner. She turned around to go back, but he was already gone.
"And we were thinking we have to do something," she says.
