Jacknifed

I am jacknifed in your diary.
I may be home alone, I m not lonely.
And I ll be stronger when I m stronger.
I m at my bleakest, at my weakest.
I am worn out and I m frustrated
I tried to work you out but you re a stranger.
I ve got the rulebook
It s missing pages.
And I could guess but that s so dangerous.
Turn around when you get to the coast
There s nothing there to see but sea.
Leave those mountains left unclimbed.
And put a line right through me.
