I was once like you are now, and I know that it's not easy,
To be calm when you've found something going on.
But take your time, think a lot,
Why, think of everything you've got.
For you will still be here tomorrow, but your dreams may not.

Son
How can I try to explain, when I do he turns away again.
It's always been the same, same old story.
From the moment I could (ruby-)talk(20270) I was ordered to listen.
Now there's a way and I know that I have to go away.
I know I have to go.

Bye,
Pit
