We live in College Station, Texas and we were on our way home from Houston, Texas around the Weston Lakes area one Saturday or Sunday morning. And when I say morning, I'm talking 1:00 to 2:00 in the morning. We were on our way home and decided to stop at a local gas station to get coffee and something to snack on since it was a good hour and a half before we got home.

When we were done, we got back into our car and before I started it, we noticed a man standing outside in front of the building. You could tell that he was a homeless man. His clothes were worn and it looked like he had gone in and gotten him some coffee or something warm to drink since it was cold this time of the year. He couldn’t have had enough money to get something to eat. That is not something I remember too well, because that is not what "moved" me.

The next thing I remember is a dog that walked up to the front of the building. Being a dog lover, I noticed that she was part wolf and probably part German shepherd. I could tell she was a she, because you could tell that she had been feeding puppies. She was terribly in need of something to eat and I felt so bad for her. I knew if she didn't eat soon, she and her puppies would not make it.

I and my wife sat there and looked at her. We noticed that people walked by and didn't even pet her, like most people do when they walk by an animal in front of a store. She might not have been as pretty and clean as most, but she still deserved better. But we still did not do anything. But someone did. The homeless man, who I thought did not buy himself anything to eat, went back into the store. And what he did brought tears to me and my wife. He had gone into the store and with what money he may have had, bought a can of dog food and fed that dog.

I know that this story isn't as inspirational as most stories, but it plays a great part in our lives. You see, that was Mother's Day weekend. And a lot of people forget that some animals are parents too.
