I agree with everything that has been said. I often look at family photographs and think about how several generations have come and gone between when the pic was taken and now. I like how you talked about electricity as the life force of a home. It's a great analogy. Electrical circuts are somewhat like the circulatory system. Seriously, I can't imagine life without electricity, and it's been around for so long that any home without it is dead. It's like a cave or something. You also need someone to turn on the lights, and a what is a house if no one lives there? I hate to even look at vacant houses. I also like how you didn't go into why the people are dead. I think a womb is a great metaphor for a home too. It's like a second womb. I think you have an agreement error:
Houses Left alone To wait for life to Come back to Their womb
You say houses and then say their womb. I think it needs to be wombs. This is a bit like my poem Cold Paper Time Capsule, but the imagery is better. I like this very much.
