Delighted by, made her delightful; Conversation flew. Tea roses made her face go smiling. This is all she knew: Porch talk is made for happy listening (Sorrow we eschew), And roses made for much admiring. This is what she knew.
Thomas McAfee sketches a woman whose whole world seems to be porch conversation and tea roses. She is "delighted by" the things around her, and that delight is what makes her delightful in turn. Talk flows easily, and the roses seem to put a smile on her face. The first few lines are a little tangled, as if the grammar itself is too relaxed to bother completing the thought, which suits the easygoing mood.
The poem circles back on itself, ending with the line "This is what she knew," which echoes the earlier "This is all she knew." That small shift from "all" to "what" is worth noticing. Her knowledge is narrow, built from pleasant talk and admired flowers, and she deliberately shuts out sorrow ("we eschew"). The speaker doesn't openly judge her, but the repetition leaves you wondering whether her contentment is a gift or a limit. The overall feeling is warm, gentle, and a touch wistful.
