What always puzzled me was the how the " background noise" always went eerily quiet seconds before it kicked off. The "background noise" could be chanting, singing, goading, fans gobbing off, or just general chatter between fellow fans. It could be inside or outside the ground, before or after the game, in a pub, on the terraces, walking to the ground, wherever. I called it a mix of experience, being street wise and a 6th sense. Whenever the background noise went eerily quiet, you had a choice......get away asap or be in the thick of it within seconds. Can anyone else relate to this or was it just me?
