Not exactly a den of hate, but I got in the Fulham home end a few years back to watch us beat them 4-2, when Xabi waded in with a great performance after being 2-0 down at half time.
I did exactly what theredworm did, sat on my hands for most of the game but I broke and couldn't help myself jumping up out of my seat when Xabi's free kick went in to make it 3-2. I was in about row 5, so there was a whole stand behind me when I jumped out of my seat. I realised my mistake just about as my knees locked in straight extension and so I came out with "Oh For FUCKS SAKE" and looked around behind me with a nasty fed-up look on my face. All eyes on me, I don't think they all bought it but I think they let me be because I didn't cheer it.
A fellow red was ejected across from me early in the first half and a group of home supporters were up on their feet shouting and threatening him before a steward grabbed him out.
The day was capped off as I witnessed the solar eclipse of any Liverpool fan's career, seeing Biscan score.
