020 Chapter 1.11 Sewers are fun...

If you're ever in the dark, there are a few sounds you don't want to hear. One is the sound of a gun being cocked, one is the theme to The Twilight Zone, and one is hissing.
I hate hissing.

On an aside. There is someone that I have intermittent contact with who is constantly hissing.
I'm serious. Every time he passes by, he is blowing air through his teeth making hissing noises unconsciously.
OR he may just speak Parseltongue.
Either way, not a very endearing trait. Just sayin'.
