My friend invited me over to his house to wash the car together for fun. Instead of going to the shop, I didn't expect that before I could wash anything, my friend's wife was so carefree showing off her goods that the nightingale kept singing and couldn't wash it. So he cooperated with his friend's wife to make the nightingale happy :D.
