In other words, we all gotta go sometime. And a lot of times, these lines sort of elide into only that sentiment – but there’s a development here that’s possible.
There can be optimism sprinkled in. As in: Listen, at least if I die now, I don’t have to worry about it coming later. If it’s not happening in the future, it’ll be now. And if it’s not now, it is definitely coming for me later. There’s something to work through – and I appreciate the sort of sestina quality of this line – circling around itself to say something both different and the same.
