Do I have any run-on sentences?
Well in "I dwell in possibility" it is more joist, Nature, Imagination, and Creativity. Unlike in “Do Not Go Gentle into That Good Night” there is innocent death, war, The lessons of age, Grief, Defiance of Death, Anger, and Late-Stage Regret, the two poems have a few things that are the same as Inherent Value of Life, Inherent Value of Life, and defiance. So from this list, you can see that poem A which is “I dwell in possibility” is a happier poem than poem B “Do Not Go Gentle Into That Good Night” which is more about how he wishes the people he had lost were there with him but they can't well poem a is talking about how he is happy to be where he is wall maybe poem b is talking about war and death and maybe even a war with his heart and mind.
