A Proper Goodnight

I wanna say a proper goodnight
But not now,
Maybe later tonight,
But what if she'll be sleeping by then?
Or what if she asks me now
why am I not saying a proper goodnight?

Should I say it now?
What if she's not going to bed yet?
Will she think I'm sleeping already?
What if she thinks she's boring me?

I wanna say a proper goodnight,
But what if she doesnt like it?
What if she already sees it now,
Have I blown the surprise?

Damn
So many things...
Why can't I just say GoodNight?
