Who are you?

I have a pulse.
It quickens when you're near.
Perhaps it speaks too softly;
Perhaps you are too loud,
    'Cause I can barely hear.

I dream of times I've gone away
To see the skies So Clear.
Yet returning always feels like Home,
    But Home is nothing Dear.

Good Times I've had
    And bad Times, Too.
Sometimes I wish I'd seen it ALL.
Sometimes I wish I'd seen you.
