The poem begins with a general idea: beauty, truth and love are almost impossible to notice when we shut ourselves off. The speaker pictures someone with closed eyes, plugged ears and a heart "tied up in knots," unable to take anything in. Then Anne walks into the room, and everything changes.
From there the poem becomes a series of small, warm details: her sheepish grin, her crinkling eyes, her glow, her laughter, her kiss. The speaker admits to being "greedy," wanting to soak up her whole essence, and reaches out to touch her face. The mood is tender and happy, with a little breathless wonder in it.
The ending is the neat part. The opening list, "beauty truth love," comes back reversed as "love truth beauty." That suggests the speaker has moved from blocked-off to fully open, and that loving Anne is how he finally sees those bigger things. Receiving her and giving in become the same act.
