Sixteen years ago, I learned an important life lesson in the back of a New York City taxi.

I was on my way to Grand Central Station, and we were driving in the right lane when a black car suddenly sped out of a parking space right in front of us.

My driver fit the brakes hard, skidded, and missed the other car by a few inches. The driver of the other car, the man who had just nearly caused a huge accident, started shouting at us. My taxi driver just smiled and waved at him. He was really friendly!

“Why did you just do that?” I asked him. “This guy almost destroyed your car and could have sent us to the hospital!”

This was when my taxi driver told me what I now call “the Law of Garbage Trucks”.

“Many people are like garbage trucks. They run around full of garbage, full of anger, and full of disappointment,” he said. “As their garbage piles up, they need a place to dump it, and if you let them do, they’ll dump it on you. So when someone wants to dump on you, just smile, wave, wish them will, and move on. You’ll be happier because of what you have done.”

I started thinking, how often do I let Garbage Trucks run right over me? And how often do I take their garbage and dump it on other people—at work, at home, or on the street? It was on that day that I said, “I’m not going to dump anymore.”

School had just started in August when Conner began throwing up for no reason. It wasn’t long before the boy also began suffering terrible headaches. In February a 1.7-inch tumor was found in his brain and Conner was set to begin to receive radiation (放射疗法) treatments. Before treatments start, technicians make a white plastic mask (面罩) to keep patients immovable and protect unaffected parts of the brain while radiation is directed at the tumor.

It’s an unpleasant experience and a frightening time. The doctor Cook decided that the masks could at least be made to look like something fun — maybe Batman or Mickey Mouse. “I started thinking these masks are white and not fun at all for kids,” she told The Greenville News. “I felt like if we could make it a little more fun for them, they might be a little more excited about coming in for the treatment. Because the kids are afraid. While the treatment itself isn’t physically painful, it can cause a lot of anxiety (焦虑). And the treatment is required daily for up to six weeks. “

And the masks really make a difference. “The kids really like them,” Cook said. “It makes what is, let’s face it, a terrible experience, a nice experience because they get to choose something themselves.”

When new children come in for the treatment, Cook finds out what their favorite movies or cartoon characters are. Then she sets about creating the mask by drawing the image she wants onto paper, sticking it with glue, and once it’s dry, she applies the colors using paints. Each child can take the mask home once the treatment ends.

“Coming to the doctor always means fear and pain. I wanted to make it fun,” she said. “The kids really love it. It’s something they enjoy and can relate to. And it fills an interest I have. I get great pleasure from it.”
