Song Chen cried out in pain. "You cruel woman, without me to warm your bed, wouldn't you feel lonely and cold?"

While Lin Lu was preparing lessons, she listened to him chattering like background music. All she had to do was reply with a few words here and there, and he would keep talking like a stand-up comedian.

In the end, he felt thirsty and asked Lin Lu to wait for him for a while, drank some water and came back to continue.

Lin Lu: "Okay, go ahead."

His eyes were not on the phone, but his hands were still writing.

Unexpectedly, Song Chen changed after he came back from drinking water, "How long will it take you to finish writing?"

Lin Lu: "Right away."

Song Chen: "Okay, I'll wait for you to finish writing, then it's your turn to speak."

Lin Lu stopped writing: "What are you talking about? I'll tell you."

Song Chen: "Can you tell me what you did today? Did you miss me?"

Lin Lu said with full energy, "Get lost."

After preparing lessons and taking a shower, I came out and lay on the bed, but he still hadn't hung up. No wonder his monthly phone bill is several times higher than others.

Lin Lu actually told him what she had done today, but it was like a diary, without any emotion: "After you left, I went to the cram school and taught the students. Then everyone was riding their bikes over there. After they finished riding, Ah Bei and I came back."

"Bike?"

Song Chen was puzzled: "What kind of bike are you riding?"

Lin Lu forgot to tell this person that Lin Jingbei and Xu Weichang were researching electric bicycles.

He smiled proudly and said, "Your son has made great progress. He and Teacher Xu have researched an electric bicycle. It runs quite fast."
