Am I a music snob?

So I've started creating a list of concerts I've attended. I'm not sure whether to just start from my very first one and work my way forward with my memory or just start writing down any and all I can think of and sort by years later. For this reason, I haven't actually written down anything on paper yet, it's all up in the head thus far. My friend Carren told me to attend the U2 3D concert at imax and so I took my father and two sisters last night. It was a sold out crowd and there were 6 people total (including us four) that actually clapped and acted like it was a real concert. I actually stuck out my hands a couple of times to touch "The Edge" and Bono but to no avail. I suddenly realized that no one else in the audience was treating this properly. I mean it demanded clapping and shouting and putting my hands in the air with the "rock" symbol and so I did. Are Seattleites such music snobs? After all, this is the land of (look to list at right). Or am I music snob and demand perfection from crowds. I know we all "feel" music differently, but not even a little clap at the end? Were they not feeling what I was feeling? Were they not U2 fans? It's like if someone I love dies and you walk into a grocery store and you expect everyone else to be sad, and you can't figure out why everyone is in a chipper mood. Were my expectations just too high?
