Brother-in-law borrows the car.

As the saying goes, neither the car nor the wife is lent out. Although this metaphor is inappropriate, it illustrates the importance of cars. I really need to talk to your wife. Don't try to engage in relationships, be merciless, save fuel and so on. In case the car breaks down slightly and there is a minor accident, the owner himself will bear the main responsibility. Unfortunately, two families will be involved.
