My son is in the airforce. He often tells me about the "random thank-you's" he gets from people. People that walk up to him, and say "thank-you for what you do".
Today he told me he was in the grocery store picking up a few items, and he was chatting with a gentleman while they waited in the checkout line. The mans daughter was stationed in Iraq. My son called to tell me that the man paid for his items. He said to me, "Who does that? Who pays for someone else's groceries?"
I said, well, there are still very nice people around, and with a daughter in the service he knows military personnel are not exactly highly paid.
This was well beyond a "random thank-you", so, whoever you are, thank-you from an appreciative mom.
