Wow, Tums it's hard to not get choked up!
It sounds like you're discovering how deep something like that goes, but behind the scenes, the stories those kids and folks are telling and the feeling they have inside and will carry with them (as well as you), in many cases goes deeper than we can imagine. And if a picture tells a thousand words, you just filled a book with no ending.
I don't know if the T-shirt this young man is wearing dons a hero of his, but note his grandpa in nearly the exact same pose!
And for just losing a son and a dad, imagine the emotions they're feeling at that moment.
Hats off to you and thank you for inspiring the rest of us.
Way to pay it forward!
