Such a sad poem :)
The word usage was great. The length is good and so was the flow for the most part.
There were some places where you have to read carefully so as to not get lost but other then that it is a great poem.
I love the string imagery of that rain, and of you dancing in it, even though it is soaking through you, it somehow reminds me of your loved one that you are missing, and how you feel a presence of them here.
The opening of sky, when you see them, is so touching! Such a gripping thought to know that you can feel so close, feel even able to touch them, but then just like that they disappear. So capturing of what it feels like to hold on to a memory, but then to lose it again, it sometimes feels like losing the person all over again.
Such a beautiful story and the loss of relationship could be put towards any bond actually, parental/friendship or love.
