Jesus, you miserable f**ker.
I am a die hard festival goer, as you may know we have our own Glastonbury here every August called Electric Picnic and I've been to 10 out of the last 11. Some of the most life affirming moments of my life have happened at festivals, in a crowd of 10,000, singing every word, hands in the air,hugging the randomer beside you for the chorus, passing spliffs around, watching the sun go down in the campsite whilst dropping pills and knowing that the next few hours of your life will be spent with the greatest people ever, listening to the greatest music ever (at the time) and then whiling away the early hours in the woodlands at the various raves/installations/tents arm in arm with those closest to you.
I don't understand why people want to wish rain and misery on people who are out to have a good time at no-ones expense. If you can't make the festival yourself, fair enough, but don't wish rain etc. rain is a fooking nightmare at festivals.
