This is Samantha Ford and her boyfriend, Albert DeSimone. They've known each other since they were in the 5th Grade. Albert is an Army Specialist and was deployed to Afghanistan last September.
Earlier this week, Samantha went to this Arlington, Massachusetts Dunkin' Donuts.
While she was in there, a passerby noticed this sticker on Samantha's car.
What Samantha found on her windshield when she returned to her car left her in tears.
Samantha posted the above photo on a Facebook page called Our Deployment, a support community for military veterans and their families. The photo is well on its way to 2 million likes.
Says Samantha, "If I can't find them, I just want them to know that we are very grateful and completely touched by it. I can't think of anything to do but pay it forward and let that person know they made a difference."
