They are well-intentioned. For the most part. They walk into the park in their little groups, merry with lager and rum-and-coke, laden with sleeping bags and thermos flasks and rolled up ground mats. They’ll huddle together with their fellow do-gooders, music and torch shenanigans keeping them amused. They won’t sleep a wink, of course, but that’s not really the point, is it? They’ll have a tale to tell, a shared experience, something to post on their Facebook timeline. They’ll raise some money of course, let’s give them their due. Not that any of it will reach me, huddled on my bench on the less salubrious side of the park.
