Ahummingbird’s nest was swaying precariously on the tip of a slender cactus branch on our front porch. I looked at it and then went to say something ridiculously optimistic to my husband – Look, honey, a hummingbird is bringing new life our way. But, given the diagnosis he’d finally gotten from the doctor that morning, I myself wouldn’t have believed what I was saying. Deep inside I didn’t feel like anything new was heading my way at all. Deep inside I was afraid that my husband’s Parkinson’s disease, like the hummingbird’s nest, was too heavy for the branch.
