Feng Haidong said seriously to his son, "It's not possible now. No one can know that Mommy is pregnant. We have to wait until the baby is born before we can let Mommy come home."

Feng Qifan nodded and said, "Dad, I know, Auntie told me."

Feng Haidong said, "So we can't rush things now. Mom can't go home for the time being. She's at her grandparents' house and is being taken care of by her grandma and aunt. She's very safe there."

Feng Qifan asked, "Dad, after Mom gives birth to the baby, can we bring her and my sister home?"

Feng Haidong nodded and said, "Of course, maybe when Dad makes money, our family can move to a bigger house, and then you and your sister can have your own room."

Feng Qifan was very excited when he heard that he would have his own room: "Really? My sister and I can have our own rooms?"

Feng Haidong said, "Yes, when Dad makes money, he will definitely buy a big house. Then you and your sister will each have your own room. You can practice the piano in your own room, or do whatever you like in your own room. Mom and Dad won't bother you."

Feng Qifan said, "It's okay. If Mom and Dad want to find me, they just need to knock on the door. I won't stop them from coming in."

Upon hearing his son's words, Feng Haidong burst into laughter: "Hahaha, you little rascal, you even know to knock on the door!"

Then Feng Haidong promised his son, "Okay, Dad promises you, once you have your own room, Mom and Dad will knock on the door before entering."

The father and son sat on the bus, imagining what it would be like to have a big house in the future.
