When I was at a small lock-in mental hospital I wanted to sleep in so I put a little note on my door not to bother me in the morning (they wake you up to see if you wanna join whatever group activity is happening).
It worked for a while but then a nurse knocked and woke me up saying she had to and I yelled the loudest FUUUUUUUUUUUUUUCK and was never woken up again
