Thank you so much, what a compliment to be compared to them!
I had a lot going on in my mind at the time, lot conflicting emotions, and giant heap of restlessness. I wanted to give some kind of form to all those things I couldn't verbalize.
I guess you could say the hands were a kind of representation of the emotional turmoil I was in. Apathetic on the outside, but raging on the inside, before finally settling into a state that "saudade" describes.
Anyway, I hope that answers that for you, I have a hard time putting things in words in a way that is understandable for people other than myself, but I tried!
