Frank Lloyd Wright was the champion of organic architecture, a style of building meant to harmonize with nature. But I’m not sure harmonizing with chipmunks — small American animals similar to squirrels with black lines on their fur — was what he had in mind.

During my years with the US National Park Service, I spent six months working in a visitor center designed by Wright’s firm. Several other employees and I staffed the park’s phone and radio system from a room in the basement.

I was sitting at my desk when I first heard a sound in the suspended ceiling. Dark shapes moved fast across the light panel(光板) above my head. Moments later, they ran back in the opposite direction, leaving me with an impression of noses and tails, each tail followed by another nose. It was like watching a shadow puppet(皮影) performance, but with real animals.

“Baby chipmunks,” a fellow told me. “They live in the ceiling.”

After four summers working in the parks, I had grown accustomed to sharing indoor space with wildlife. Chipmunks in the workplace even seemed to be a joy; their behaviors provided a bit of stress relief on difficult days.

As summer progressed, the shadows chasing each other across our lights grew bigger. Their movement across the light panels had become more of an athletic running.

I had just answered a call one day when I heard a loud sound, and a ceiling panel fell down on my head. I dropped the phone as I fell out of my office chair, looking up just in time to see a brown tail disappear over the gap in the ceiling.

I pulled myself off the carpet, laughing with my co-workers, and noticed the phone hanging over the side of the desk. I picked up the phone, preparing to explain the crash, the scream, the dropped phone, and the laughing to the listener who was about to visit the park.

“I’m sorry, but you’re not going to believe what just happened.”

I don’t think he did.
