This story is one of my classics,
We went camping in Glastonbury, (town not festival) and arrived around mid-day. Huge field empty, chose our spot, then decided to have a nap (not a euphemism!)
We were roused from sleep to find a party of about 20 people setting up camp nearly on top of us 
They had put the windbreak so close to our door we had to slide out sideways, I kid you not! They partied all night with the exception of the teen in bed right next to us who called her every friend and acquaintance back home in Birmingham to complain vociferously about being forced to go on holiday!
The next morning a friend helped DP and I to take out the tent pegs, pick up the tent and move it to the other side of the site.
As we sat having tea in the evening a Maestro pulled up next to us and out came an elderly couple. They got out a double air bed and bedding and nothing else and disappeared inside.
Soon the unmistakeable sounds of passion were heard and we grinned as we went off to have a shower and change for supper in town. Still going strong as we got back, cue knowing nods from fellow campers.
When we got back at midnight still at it, very loudly! Still at it when we fell into dose around 2am ish. There was a plaintive cry at some point of, 'Can I stop now?" Answered by, "But darling it is SO lovely" and on it goes.
Blessed silence greeted the dawn, then the dawn chorus broke as the mists cleared over the Levels. Our couple too were early risers because away they went again!
About 8.30 they emerged, deflated the air bed, put down the rather large frame tent and back into the Maestro they went!
We were exhausted, 2nights with no sleep 
We went out that evening but home and tucked up by 11pm.
At 1am a young couple started screaming and shouting. Then car doors slam and the car zooms off! Cue shouting and yelling by young man who says she has got all his clothes. I peep out and yes it is true! Goes on, he gets wilder, the. police come to calm him down and return him to the tent. All quiet until about 4 am when he is heard wandering around muttering about knives, holding a conversation with an invisible person generally scaring the doodah out of us. A brave soul, (who later discloses she is psychiatric nurse) comes out and calms him down until the police return and take him off!
I have never been as tired after a holiday; we got in the house mid-afternoon, fell into bed and didn't wake until the next day 
This was one of our first visits to Glastonbury; now I go in search of sanctuary and healing and find it, though when I remember this camping trip I do wonder why we went back!
