We'd watched "night of the living dead" (old B&W zombie film) and she was petrified. While she went to the loo I thought it would be funny to stand outside the door in the dark with my hands outstretched and a zombie face on (I do it really well)
She opened the door looking back in to the bathroom and heading out (not looking where you are walking in best 'scary film tradition') and turned her head round just as she came face to face with me. I've never heard anyone scream like that before in real-life, or seen anyone collapse on the floor in quite the same way. It's also possibly the longest stream of swear words I've heard in one go.
If you think that was a good reaction, you should have seen the one I done to somebody. We were working nights in a phychiatric wing of a maximum security prison when I done the same to him. He hit the ground so fast I thought I'd killed him. We're still good mates though...
I'm a kind of a coward sometimes
You just need someone to snuggle up to when your watching them.
