Please explain all of the plot elements of There Will Come Soft Rains.

In the exposition, the fully robotic, automated house is
going about its daily business. Only, something isn't right. There seem to be no humans
for it to serve. An outside view of the house shows burn damage to one side. And, in
that burn damage,three silhouettes are burned into the image like a negative in old
photographs: A man mowing, and two children playing. At this point the reader is
supposed to come to the conclusion that there was a nuclear blast that killed the people
and left the house standing. This is not an unusual occurrence in nuclear aftermaths.
Eventually the house's robotic systems begin to break down, as there is no one to
monitor and service it. The house catches fire, and burns to the ground with the last
robotic voice silenced. The title refers to a poem by the same title. In it, the poet
expresses that nature will not notice when mankind becomes extinct. Nature will continue
without us.
