The poem is built from three "if" statements and one plain answer. The speaker imagines a few bleak or oddly comic possibilities: eating alone, being buried with a hat still on, and believing that god is no more solid than a paper bed. Each one touches something unsettling, whether loneliness, death, or a faith too flimsy to rest on. But none of them changes what happens next. The speaker gets up in the morning.
The tone is quiet and a little wry. The hat in the grave adds a touch of stubborn humor, as if the speaker plans to meet even death with some dignity or habit intact. The paper bed is a fragile, striking image, suggesting comfort that could tear at any moment. Still, the final line doesn't argue or complain. It simply states what is done. The mood is one of low-key resilience: no big hope, no despair, just the ordinary act of starting another day despite uncertainty. The title, "Sunny," may add a dry note of brightness to that.
