This is seriously one of the best #BlueLivesMatter stories you'll read. And it's really nothing more than a simple gesture. Sometimes, that just speaks volumes.

People spend a lot of time behind their keyboards talking about what needs to be done and how #BlueLivesMatter, #BlackLivesMatter, #AllLivesMatter, #TheyLiveMatters, etc. They then shut off their computer and go on about their lives, feeling like they've done something positive. They haven't.

This teenager saw a Texas Deputy pumping gas by themselves. After the assassination of Texas Deputy Darren Goforth, he thought the Deputy could use back up. No he didn't tweet a hashtag, he acted.

Harris County Deputy Constable Tommi Jones Kelley posted the photo this week to Facebook and wrote, "this teenager I've never met before is standing right behind me & says, 'ma'am, do u mind if I stand here behind you while u get ur gas?'"

She asked him why. The young man, whom she identified as Mckinley Zoellner, answered "to make sure You stay safe!" Kelley wrote. The post had been shared 181,000 times by early Sunday.

The gesture delighted Kelley, particularly in light of the killing of a sheriff's deputy at a gas station a little over a week ago.

Thank you Mckinley for not only showing us that #BlueLivesMatter, but also showing us that, heck, being human matters. Human beings matter. Actions speak louder than hashtags.

All lives matter. Only the people who truly understand that can even say that "black lives matter." Otherwise, it's just identity politics 101.
