Grumpy Old Man

**KNOCK KNCOK**

Su Anya knocked on the door. Since they come from the class, Su Qing had closed herself inside the room.

"Su Qing open the door. At least tell me what have I done that made you so upset." She said.

She rubbed her temple and helplessly looked at her brother. "Call her out. She would listen to you."

"It's me open the door."

After a few moments of tense silence, the door slowly opened. Su Anya was left speechless as she realized that it had taken her brother just one sentence for Su Qing to open the door, whereas she had been knocking for nearly half an hour without any success.

Once inside the room, they noticed small pieces of paper strewn across the floor - Su Qing's drawings from class earlier in the day. Su Anya picked up one of them and asked her in a gentle tone, "What is this?"

After opening the door, Su Qing lay down on her bed with her face covered with a blanket.
