actually if this situation ever happens, I would try to figure out who they are first especially that they are just strangers. as long as I can get much information about them... I will proceed to help them, but if I could think of a way to refuse... then I would ask my family to handle the situation instead.
Basically list one critical approach from the assigned readings ... okay then what approach of criticism / critical approaches would go with the poem and explain why u think it goes well with that poem , hope that helps :)
