Three short lines give us a small, vivid scene: a gusty day, someone walking down the street in reverse, and a quiet complaint about a bad leg. The title, "Gimpy," names the limp directly, and it sounds like the speaker teasing themselves rather than asking for pity.
The poem doesn't explain why the speaker walks backwards, but the first line suggests an answer. Turning away from a strong wind is a natural thing to do, and perhaps it makes the walk easier. Yet it's an awkward way to move, especially with an injured or weak leg. The phrase "my poor leg" reads like a sigh, half sympathy, half exasperation, as if the speaker is talking to the leg itself.
The mood is wry and gently comic, with a touch of vulnerability underneath. There's something stubborn and good-humored in the picture: the wind is pushing, the body is struggling, and the speaker keeps going anyway, noticing how absurd and fragile it all feels.
