Blue Star Mothers exists as an organization to provide support and friendship for mothers of those who serve. It is not an organization you choose to join; your children choose it for you. When a person joins the military, his or her mother becomes a Blue Star Mother. You've seen the flags. Mine has three stars.
Another organization also exists, to which no mother ever wants admission; the Gold Star Mothers. This organization is for those who have given a child to military service, and have lived through the experience of that child's death in that service.
When I was a kid, I noticed a poem in my mom's room. She had glass on her dresser, and, under that glass, was a poem titled Gold Star Mother. I wish I could find it now. It spoke of washing his chubby little legs, and being proud to see them in uniform, etc. I remember being touched by the thoughts of the poem.
So when I saw this photograph on Pioneer Woman's blog, I just had to share. She's been running a series called "Coming Home," and I dare you to go to her page, look at those photos and remain dry-eyed. What moving images!
