Today I was working at the animal shelter in my town and was walking the a dog around the parking lot. As I was coming back, I saw a family taking a dog out of the back of their car. The only reason people bring their animals to the shelter I work at is to give them up for adoption. This on my own made me sad, but I see it frequently enough I learn to ignore it. Then, the woman in the car looked at the puppy I was walking and said, "When we give away this dog, lets go buy adopt that one!" This made me so angry hearing her say this and think that she could just adopted and give back dogs just because she didn't end up liking them. Right then, I hated her.
<bot>: A woman acted like giving up her dog for adoption and just choosing a new one was not a big deal, and it made me think bad about her.
