There is someone, someone who I presume is literate, has good choice in books, and who is sufficiently able as to visit the library. This person, believe it or not has the most disgusting perversion I have ever come across(and that’s saying something.) This person takes books out of the library, mainly detective fiction. Not only do they Bowdlerise these books, crossing out any obscenity, but, and it’s a big BUT, they leave snot on the book pages.
Yes, this person picks their nose and wipes the boogers on the book pages.
If I ever find out who they are, I will write a note to them; this note will read “DO NOT WIPE YOUR SNOT ON LIBRARY BOOKS”. In order to ensure they do not forget this instruction I will nail it to their forehead with a six inch nail.
Seriously though, you are a very sick person mate. Get yourself assessed.
