The wind and son

For the boy who's left behind: you are the air.
You are the heir, and you've inherited the sky
It's slowly filling up my eyes
I can't hold on if I try
The sighs of size, oh
The size of sighs
I'll lend you a hand you my heart in my mouth has run out of things to say, of secrets to give away
For the boy who's left behind, this comes to you by air mail
Whispered in your ear.
