A nervous wreck.
First he lies on one side, then he lies on the other. Credit: Nicholas Sparks from his book 'See Me' which I am reading now.
A dead centipede.
Because not even Nightbot is watching you.
Because the beach never waved back.
Nothing, it just waved.
A nervous wreck! I first heard this at xmas 1952 (64 years ago) and it still makes me smile.
