The poem catches a couple in the hazy aftermath of a night out. "After drinking / where are we" works two ways: it could be a literal moment of confusion, a half-drunk wondering about location, or a gentler question about where the two of them stand in life now. The title, "Aging ungracefully," suggests they know they are no longer young and are not behaving as if they were.
The wind comparison is a little odd. "As windy as winter" sounds like the weather, but it might also describe the loose, blustery, slightly wild mood of the people themselves. Then "married hands" slows everything down. Those hands feel familiar and settled, even a bit worn, set against the restlessness of the drinking.
The ending lands somewhere warm. The "blue / wonder bed" is cozy, strange and tender at once. The speaker seems amused and content, and the mood is playful, intimate and quietly grateful rather than regretful.
