Trying to give direction

I am as far away as a tree branch
but close enough you can hear my song.
I try mightily to mask my breathing
but holding it in as I have been told is hard;
I would rather shout nonsense
than coldly express what I see.

What I see is far too vibrant to be calm
so you may usually know where I am
even if you do not know what I am thinking.

I am lousy at being detached
so I launch myself over and over,
hoping someone will catch me.
