"That sounds nice. What kind of dog does your sister have?"
Calvin's voice has just a tinge of envy in it. He isn't entirely sure what family time consists of, but he doubts it is like the time he spends with his uncle. His mind briefly wanders back to a time when he had a more normal family as he tries to remember if he has ever had a dog. He can't remember one, but his memories of his early age are all sorts of fuzzy, and he doesn't like trying to remember them too much.
