Name of a Tree by Catherine Anderson

Some days I am Ana's teacher, some days she is mine.
This morning, we look through her kitchen window,
the one she can't get clean, cobwebs massed
between sash and pane. The sky is blue-gold, almost
the color of home.
Ana, I say, each winter
I get more lonely. Both of us would like the sun
to linger as that round fruit in June, but Ana says
it's better to forget what you used to know...
