Uninvited Guest At A Dinner Party

Who are You?
Why are you here?
You were not invited
Your methods are unclear.
Why do you interrupt our dinner?
Can't you see that you're in danger?
Mouse can run but rats smell bad
We want to eat but you make us mad.
You're an uninvited guest (This could be a test)
At our dinner party (Come and join the family).
Come on in, look around.
What are you doing on this side of town?
Check out the rooms, smell the fumes
Rats are in their parlor gowns.
