“There Will Come Soft Rains” please help!

The author does a brilliant job of incorporating dramatic irony. This kind
of irony is a little different than the "irony" we usually talk about. Dramatic
irony is when something is made clear to the audience that the characters (in
this case a house of dead occupants) are not aware of which points out some
glaring comparisons to real life. In what way is the poem “There Will Come
Soft Rains" used for dramatic irony? Think about what the poem is portraying
compared to what is actually happening. What does the poem describe and
how does it compare with what has been described thus far?
