In the early morning, I head for the back door and find 10 inches of snow covering our home. Oh no, Bryan will have to clear the roof again, I think. But Rio rolls onto his back, playing in the white snow and kicking his back legs, delighted. His days in an animal shelter in New Mexico are long forgotten—he’s wholeheartedly enjoyed life as a Colorado dog.

Rio needs a walk. I’ve planned to attend an emergent webinar, but my husband is busy clearing. Rio pushes my leg with his snout(口鼻部), wondering why we are still inside. We’re late for our morning hike. I pull on my boots reluctantly. I don’t have time for this!

Rio and I walk a block through our neighborhood to the beginning of a road. Rio jumps happily into the snow, which is up to his neck. But I walk slowly with heavy steps, worrying about my to-do list, and I don’t notice the world around me until Rio starts barking.

A squirrel (松鼠) chitters at him from a high branch of a pine tree. We haven’t seen a squirrel in at least a week because of all the snow storms, so this is a treat for us.

Once again, my animal teacher is reminding me to enjoy the present moment, and I’m grateful. I take a deep breath and look around. Suddenly there is an explosion(爆炸) of snow. a nearby tree has released its heavy burden, snapping(迅速恢复) back upright. Silver snowflakes(雪花) dust the air around me as a group of birds flees the area, talking to one another as they fly overhead.

I watch and listen in wonder for what seems like a full minute. There will be 1440 munites on this day, but this is the one I’ll remember most. Then I look back to the earth and there is my sweet dog, waiting patiently for a treat. He knows I’ll want to celebrate this moment we’ve just shared. “I love you, Rio!” I say as I give him a cookie. He has trained me well!

When we walk home, I smile broadly, spirit washed clean, ready for whatever the day may bring.
