"Ms. Wong, I feel a tear coming out of my eye."

I was confused. Why was he telling me this? What did he want me to do about it? "You're right, sweetie. There is. Can you take your finger and wipe it away?"

He did and I walked away. Less than a minute later, he raised his hand again. "Do you know why there was a tear in my eye?"

"No, hun. Why?"

"Because I'm drawing a picture of my mom and I love her a lot and I miss her."
