Thesis for Poetry Essay

It took me awhile to figure out what I wanted to write. I still struggle with poetry. I am going to try and understand the two poems "Do Not go gentle into that Good Night" and "Those Winter Sundays". I feel that they have alot in common and I will try to prove that to the readers. To me the speaker in both poems is a child that talks very proudly and positive about there father but when their father is speaking to them they show some negativity towards their father. I might have difficulty trying to come up with enough thoughts as to why I feel this way, but hopefully in the end it will all be smooth.
