Rantings of a middle aged women

Let me entertain you, with these thoughts inside my head.
I promise they won't give you nightmares, when you're lying in your bed.
If I could put a few together, then they might make some sense,
And if I could relax, then I wouldn't be so tense.
I think my guardian angel, is a devil in disguise,
And my rose coloured glasses, have just hoodwinked my eyes.
The snow is black, when I know it should be white,
And the moon is out in the day, and the sun at night.
I know I should be feeling, but what I'm just not sure
And I can hear the bell ringing, when someone is knocking at the door.
My heart it has a sign up, saying 'danger , keep away!'
'Gone to lunch-back soon-try again another day!'.
It's not that I'm not friendly, or want to get too close.
But I tried love once, not sure if I want another dose.
I'm back on my feet again, after being knocked down
And I'm quite enjoying, painting red the town.
So hang on in there baby, I'll even throw you a line.
Even a heart can mend, given enough love and time!
