...“Not Stubby” My mother has a pet squirrel named Stubby.He is not, technically, her pet, as he lives outdoors as a wild squirrel. But he spends much of his time sitting on the railing, watching my mother, and my mother spends much of her time sprinkling seeds outside for Stubby, so you cannot deny they have a relationship.While my husband, Peter, and I were up north visiting, however, Stubby had a visitor.“That’s not Stubby!” my mother said, looking out the window at the red squirrel who appeared remarkably at home.It’s easy to identify Stubby since he lost half his tail in some unknown but unquestionably tragic accident. It was shortly after the loss of his tail that my mother took Stubby on as her dependent. The other squirrels disappeared in the winter, but Stubby remained.

Stubby was thriving with half a tail, especially now that he had my mother as his benefactor.But then, another squirrel showed up. “That’s not Stubby!” my mother repeated, looking at the squirrel who was sitting where Stubby always sat, eating the seeds put out for Stubby.“Maybe Stubby has a girlfriend,” I suggested. “Maybe this squirrel chased Stubby off!” my mother said, apparently far less optimistic about Stubby’s chances for romance.But Stubby was missing. I just was beginning to believe my mother’s theory when we spotted Stubby a short distance off. He was eating pine-cone seeds, giving the visitor a little space, but apparently going about his business as usual.“It’s very odd,” my mother concluded, wondering if she now had two red squirrels to support.But the red squirrel only ...
