But lots of times we are.
3 things we often bitch about...
1) the lack of participation in our sections
2) the lack of participation from sections around us
3) the rest of the crowd wanting to do the wave
#1 is fine. When we get lazy, we need some motivation and coming from within works. At least sometimes.
#2 runs counterproductive to seeing what we want: more participation from the rest of the crowd. Bitching amongst ourselves about it is alright. If you were Joe Prawn-eater and you were maybe just starting to dig the chants and then you get screamed at cuz you're not joining in, that's probably gonna make you less likely to join in, not more likely. Encourage or ignore.
#3 We're already standing. So why pretend to sit when the wave rolls around? Or why gripe when it you see it. You don't like the wave. Ignore it. Any other reaction harks back to #2.
