It's wrong to not sympathize with a creatures death.
Jenny's dog has just recently died and Jenny tells her friend Dave about the sad news.
Dave wants to react to Jenny telling him her dog died.
Dave tells Jenny that the news is terrible and that he feels really bad for the poor dog.
Dave tells Jenny that it's fine since it's just a dog, not someone important like a human so not to worry about it so much.
Jenny is a little uplifted by Dave's sympathetic and kind words and feels slightly better about the situation.
Jenny is unhappy that Dave is trivializing the loss of a loved pet and starts to get scared that Dave is a sociopath.
