 Mother and I agreed , when we talked about it , that Dad never meant his poem to apply to one particular tree , or to the trees of any special region . Just any trees or all trees that might be <unk> on or <unk> on , and that would be suitable nesting places for robins . I guess they 'd have to have upward @-@ reaching branches , too , for the line about ' lifting leafy arms to pray . ' Rule out weeping willows .
