I still remember clearly watching it all unfold live on RTE as an 8 year old and it was horrendous then but more so as the years went by and I learned what really happened.
I think the reason it has some sort of affect on football fans, not only Liverpool fans, is because it could have happened to any group of supporters. If the Nottingham Forest fans had been given the Leppings Lane end that day, they would have suffered the tragedy. If the other Semi Final had been played at Hillsborough instead of Villa Park, it could have been Everton or Norwich fans. This tragedy was looming for years as many older football fans who attended games in the 70s and 80s have stated. Had it been a few years later in the 90s, when it was more accessible for Irish fans to go to games in England, particularly match trips organized by local youth teams, it could have been someone you know. As unlikely as that scenario may have been, it wasn't outside the realms of possibility and that's why all football fans are somewhat, however little, affected by the fact that 96 people went to watch their team and never came home.
