Everything seems just fine on the surface in "Sestina." The grandmother and grandchild are in the kitchen making tea and having an afternoon snack together. Cozy and cute, right? But something is totally off here. The house is cold, and there seems to be all sorts of forces keeping this from being a happy home. Where is the rest of the family? Why is the grandmother so sad? Why is she hiding it? Despite the stove and the tea, everything has a sad chill to it, and we can't help but wonder if this home isn't broken.
It actually is a happy home, it's just a rainy and chilly day. Stop making something out of nothing.
The child has been abandoned by the rest of her family and the grandmother is sad and worried about their future. That's why they're both so down in the dumps.
