Jealousy can be a Good Thing.
My wife is jealous of our dog.
First off, to be clear, I’m a dog person. See, I just like dogs; my dog, other people’s dogs, any dog. My wife mostly just likes ours. In fact, she loves her (the dog). She loves me too, I know that. I love her too (my wife that is), but I really love our dog.
You see, my wife gets jealous of the attention and affection I show our dog.
