Given who I think wrote this, you almost have to know their situation to get the full context. I think this is supposed to be a set of haiku, but a couple of the lines are off one syllable. I see the part about encountering old things you can't necessarily part with but won't ever use again, and the part about losing inspiration, but I don't see the connecting thread, unless it's just generic aging. Particularly that last line: does it refer to the items in the boxes dying through disuse and decay? That's easier to buy than it being the people themselves, though the language supports the latter. The reason it's harder to buy that way is that it makes a judgment about their lives without the evidence. It would tend to mean they didn't leave the house much, but that doesn't equate to poor quality of life, so we'd need the additional piece to get there.
