A man walks into a bar. ‘Why so glum?’ asks the barman, as he pours him a beer.
‘I woke up today. I’m walking on a glass floor. Below me is the starry night, and no directions for which way I should go.’
‘Has no-one left you a note?’
‘I’ve found some scraps of paper with scribbles on them, but nothing coherent, and most of the scraps don’t agree with one another.’
‘Then better to relax a little, take things one step at a time. Let’s see if we can work this out.’
