Which statement in this excerpt from fever pitch by nick hornby shows that the author learned to have high expectations in life only after he went to a football (soccer) game?

i'd been to public entertainments before, of course; i'd been to the cinema and the pantomime and to see my mother sing in the chorus of the white horse inn at the town hall. but that was different. the audiences i had hitherto been a part of had paid to have a good time and, though occasionally one might spot a fidgety child or a yawning adult, i hadn't ever noticed faces contorted by rage or despair or frustration. entertainment as pain was an idea entirely new to me, and it seemed to be something i'd been waiting for.

it might not be too fanciful to suggest that it was an idea which shaped my life. i have always been accused of taking the things i love - football, of course, but also books and records - much too seriously, and i do feel a kind of anger when i hear a bad record, or when someone is lukewarm about a book that means a lot to me. perhaps it was these desperate, bitter men in the west stand at arsenal who taught me how to get angry in this way; and perhaps it is why i earn some of my living as a critic - maybe it's those voices l can hear when i write.
