Some students in the Spring Branch Independent School District in Texas dreaded lunchtime. The school cafeteria meant humiliation because their parents couldn’t afford a hot lunch.

The alternative for these kids was a cold cheese sandwich. Anyone seen leaving the lunch line with that on their plate was marked as being poor.

But that changed when school volunteer Kenny Thompson (right) saw it happen. Kenny recently told that story to kids he works with, 13-year-old Gary Barber (center) and 15-year-old Dakota Gibson (left).

Thanks to Kenny’s efforts, two school districts in Houston have changed their lunch policy. Now all kids receive the same lunch, whether or not they can afford it.
