When Worlds Collide

As you enter the pet store, the sounds of excited animals fill your ears. It's like a blow to your ears, but you stay, looking at the many animals that peer eagerly towards you, hope filling your eyes. You didn't plan to buy anything expensive, yet their presence comforts you, so you stay, playing with each animal, hoping you would pick them. You smile, they glassy eyes wide, looking up towards you.
What do you see in their eyes?
