This is as emotional as it gets, as far as I am concerned.
My eyes are filled with tears right now, and it happens each time I watch this.
Last night, my right had, thumb and fingers were sore. I put some "stuff" on them to alleviate the hurt, and went to bed.. Somehow, I leaned my eye on that hand, burned like heck. Would not stop.
I got up, came out here, opened the laptop, listened to this song.
My eyes teared up, again and again and again.
By the time the song had ended.
My eyes felt good.
I went back to bed.
True story.
