Answer:
The speaker uses metaphors like "keep it like a warm coat" to explain his love for her and how to treat the poem.
The speaker also adds further down the poem that he has "nothing else to give" as to show that he truly loves the reciever of the poem.
And he keeps repeating "I love you" as to remind the reciever that this poem is here to lift their spirits up and remind them that the speaker loves the reciever.
And at the bottom when he says "Keep it, treasure this as you would if you were lost, needing direction," he is reffering, agian, to show he loves her and to keep the recievers spirits up in down times.
He reffers to the "pot full of yellow corn to warm your belly in the winter" as the warm feelings that he hopes to give to the reciever of the message.
