More porch lights than usual will be shining tonight as a 6-year-old boy’s request makes the rounds on social media.

“Today” reports:

…tonight, 6-year-old Darren is asking people everywhere to leave their porch lights on “to shine a light to the moon” in honor of his father, U.S. Army Staff Sgt. Thomas Allen Baysore Jr., who was killed by enemy fire in Afghanistan one year ago Friday.

The idea started last year, the day that two men in uniform came to deliver devastating news. “Darren said he needed the porch light on so that Daddy could see he still loved him,” Jamie [Baysore] says.

And today, when Darren misses his dad, the moon is still a lifeline. “At a certain point in the day when you can see the moon, he will point it out and start talking to his dad. Or if he’s having a very bad day, he will step outside and look up and tell Daddy he loves him.”
