You wake up one day finding yourself destitute, not much on you, not much that you can do, you are now part of a crowd, a much bigger crowd, a crowd that keeps on growing and growing endlessly; you try to fit, you try to cross, to be part of a better world, to end this nightmare, but the contest is way too big, the crowd is getting bigger and bigger each day, and the inspection is getting harder and harder. Your chances are getting slimmer.
A pin between millions trying to make it to the edge.
There its role is to cross the sieve though sifting and to cross this selective border.
