Harris County Deputy Constable Tommi Jones Kelley posted the photo to Facebook and explained that she was gassing up her patrol car when she noticed the teen standing behind her.

She asked him why he was there, and he replied, "To make sure you stay safe!"

After she finished pumping gas, she says the teen just walked off and got into the passenger side of a car.

Kelley walked over to talk with the driver, who was the teen's mom. The officer told the mom that her son was amazing for what he did.

The touching gesture comes in the wake of Kelley's fellow officer Darren Goforth being tragically gunned down in while he was pumping gas.

"With all the terror going on nationwide, this reassured me there are still some pretty awesome individuals out there!" Kelley wrote.
