I feel the same way about photography-- and that is such a good point... all parts of my life seem to be focused around photography, now that I think about it. Maybe I need to live a little more. ;)
And ohhhh my god, I most definitely agree. Camera flashes are SO annoying in general, but at concerts they're just pointless. Especially with Coldplay... and all those gorgeous colorful strobes and stuff. There's no need for a flash at all, and I'm sure the band doesn't love seeing a thousand flashes go off when they perform!
