    When her classmates were having a good time, Molly sat at the picnic table alone. She remained embarrassed around her classmates. She seemed unsure of what to do or say, yet I could see her eyes longing for acceptance. Many students had already decided that her friendship would not be worth（值）the energy required to overcome the embarrassment. Others laughed at her. Most ignored her—except for one.

Brianna was making the other students laugh, as usual. “Brianna, do you see Molly down there? Would you mind walking down there and inviting her to come up here with the rest of us? I said.

Brianna sighed. I could tell she didn’t want to waste her precious time to do what I was asking of her, but I also knew her heart. She often thought of others before herself—a rare character for anyone, much less a kid.

Knowing this choice was hard for her, I pulled out a D-buck, our class currency（货币）. Though this was not the ideal way to deal with this situation. I needed her cooperation（合作）. “Here, I’ll pay you for your time.” I said to her. She offered an insincere smile, grasped the green paper, and headed down the hill.

As the rest of the children screamed and laughed, my eyes locked on Brianna as she neared the picnic table. Molly could be difficult to get along with, and I wouldn’t have been surprised if she sent Brianna back alone, refusing her invitation. When she encouraged herself to a standing position, I sighed with relief.

Minutes later, I felt a tap on my shoulder. “Here. Mrs. D.” Brianna handed me the D-buck. “Why?” I asked. “I shouldn’t keep this.” Her eyes fell to her feet, guilt showing from her quiet voice. “I don’t want Molly to think I only went to get her so I could earn the money. She’s my friend.”

A moment later, they were all laughing again, and who should I see among them, laughing for the first time that week? Molly.
