If i don't have to

You, I did it all for you
I'll do my best to teach you to fly
Please, don't cry or say goodbye
And I'll love you until the day I die
Every night if that's alright

Do you know who I am?
Do you know just what to do?
Now you're all that I have
Is it fair to love me too?

You, it hurts because of you.
And I'll kiss you through a hazmat suit
That's what I'll do if I have to

You seem to know who I am, as though you know just what to do
Now you're all that I have, is it fair to love me too?

And you, I did it all for you
And I'll love you if I don't have to
