At that time, my wife and I had just gotten married and moved into a new city. My wife was not used to being alone and always stuck to me all day long, saying that it was too lonely to be alone at home, so every time I was on a business trip, my wife would pout and lose her temper, complaining that I kept her alone at home.That time I received an order from the company that I would have to go on a business trip immediately and I would probably not be able to come back in half a month.When I went home to pack my luggage, my wife pestered me with a sad face and said that she was afraid of being alone at home, but she just refused to let me go.When I was worried, I suddenly remembered that my sister Tingting had just finished the college entrance examination and was on holiday, but she was idle anyway.So, I discussed with my wife and asked Tingting to accompany her so that my wife would not feel too lonely.
