As I post "Tree at my Window", I am inches away from a window where curtains are not drawn nor blinds lowered. But between me and the nearest tree -- unlike the scenario in the poem --I find an alley and buildings.
A message of affection directed at a tree, Robert Frost's "Window Tree" can also be read as a celebration of love between yin and yang: opposites. Much of the poem can be appreciated at either the literal or symbolic level. (The tree is concerned with "outer weather"? Indeed.)
