Paranoia

Ever got the feeling you are being watched???

The crow sits on the cctv camera at breaktime, waiting for lesson 3.

They then swoop down in murderous groups to consume what the students started eating, but never quite finished.

Of course no student ever drops litter when questioned.....

even when caught red handed some are prepared to argue that

(a) it was not them
(b) so and so touched it last so they should pick it up
(c) the cleaners/caretaker will pick it up
