Today (or "Walking Out")

Hello! ^_^

Okay, so after reading this through a couple times, I think your biggest problem here is the rhyming. Rhyming has to be completely on point for it to work in a poem. A few of your lines feel forced to fit into the rhyme. For example:

Today really did come in handy
It's all just fine and dandy

I think that your trying to say that the family here are happy in their everyday lived. The first line was, almost, completely unnecessary, but it was worked in to fit the rhyme.
In poetry, word choice is extremely important. When you set out to write a rhyming poem, you are limiting the poem's potential. I think this poem could reach greater heights without the rhyming scheme.
I think you went ahead with the rhyming scheme to give it it's lyrical quality. But this is quite a sad poem. The rhyming throws us off that. It creates a bouncy quality that works better with happier poems. For example, it works well on 'The Daffodils', but it would have seemed completely out of place on 'The Early Purges'. It can work on sadder poems, but it's all down to word choice.

Next thing I'm going to talk about is the lines after your rhyming couplets. They feel incredibly forced, and I think I figured out why. It's the lack of punctuation. It's a very stylistic choice, but I think you need some in here. At the moment, the reader is just swimming along, reading everything but taking in nothing. It's because we don't know where to pause. Line breaks =/= a pause. Because this is an emotional poem, you really want the reader to move slowly. Let them take in everything, so I think you may want to punctuate.
A fun tip: You could have the punctuation become heavier throughout the poem. It'll let us know how serious things get throughout the poem.

One thing I want to touch on lightly is your use of enjabment. The first and last stanza kind of feel like four stanzas. I think you might want to split them up a bit.

On imagery, I think you could improve a bit. The famous rule 'show don't tell' doesn't just apply to prose. If the sun is shining, I want to see it shining.

Well, that's all from me. Hope this helps! ^_^
