Abbie's poem is about a woman who says almost nothing, and the people around her can't get over it. They are amazed that she never speaks and never tries to show off her beauty. The poem seems to suggest that this is exactly what makes her striking. She doesn't advertise herself, and that restraint draws attention more than any display could.
The second half turns the idea around. Since she won't decorate herself, words do it for her: "words adorned her." The closing line, "Oh how words adored silence!", is an exclamation, and it carries real warmth. The speaker seems charmed, even a little in awe, that language itself is drawn to someone who refuses to use it.
The mood is quiet, admiring and gently playful. The short lines leave a lot of white space, which suits the subject. The slightly irregular grammar in the opening ("never speak") gives it a spoken, unpolished feel, which keeps the praise sincere rather than grand.
