1. Wife is like a family sedan, comfortable, durable, reliable, easily maintained, always ready to go distance, though she nags & mumbles once aged.
2. Lover is like a sports car, sexy looking, an ultimate pride of men. When she groans, it's heaven on Earth. But she also means high maintenance, breaks down often, and wrecks men's back over long distance cruising.
3. Soul mate is like a motorcycle, a bike makes a man out of a boy, boys're born to be wild & expressive when riding, sound of a fine-tuned bike engine is always music to young men's ears, but her charms subside once young men mature, desire for bike is often replaced by sports car.
Women shouldn't necessary be bothered by this fantasy of men, they should learn that most men can only handle motorcycle in their youth, and let's face it, most men never drive a sports car, let alone having one.
