This is a hard hitting poem for me, just from personal experience. My parents and I are the same way most of the time where we don't really show our emotions and when we do it's anger.

I can tell this is a personal poem because you are using a family member as the main character, but you are showing the reader through your observations which is a great way to use the first person viewpoint. I say this because you are using the word "dad" as a third person here.

I love the title you used here because often times when people are close to passing away they tend to be nicer or find religion and that makes them nicer. Going back to your poem however, it seems like your dad is the opposite of this and is still a mean person through your eyes. Your dad as stated above never showed his emotions well, and even when he is poorly all he can show is anger.

He has been isolated most of his life so that tells me he has always been a person hard to be around. All you can do is wait and see what happens to him.

This is a well flowing acrostic that doesn't stray from it's message throughout. Well done

ended up only one way:
Crying kids with
extra welts and a fear
in any person
that would come near.
