What are you doing at the weekend?
It's a familiar question in offices on a Friday afternoon and the responses usually vary from:
'Going down the pub with my mates, watching a bit of TV, getting to the next level in.....'
'Taking Sophie to ballet then Jake to karate then Sophie to horse riding and Jake needs new shoes...'
But rarely is the response...
'I'm meeting a bunch of strangers at Fenchurch Street station and we're all getting the train to Leigh-on-Sea for a bit of wild camping.' Which was exactly my response when I was asked last Friday.
