My nine-month optometry practice

I‘m sitting in San Miguel de Allende, Mexico, in mid-January. The temperature is 70 degrees, sunny and bright, and I’m reading online about impending cold and snow back in New York. I just called my office for an update on the practice, and I’m thinking how glad I am to be here.
