Travel by tube is generally an unexciting thing, it's often too warm and horribly crowded but recently I have noticed the phenomenon of the button pusher and it has intrigued me.... the whole tube experience is very automatic and probably for the first time ever I have felt utterly ant like in my insignificant crawling through tunnels along with vast numbers of fellow travellers. but there are amongst that number some who appear to believe they have some control over the system. They display this idea of control by pushing the button to open the train doors Ha! have they not seen that the doors open automatically regardless of human interaction?? that the whole movement is completely pointless?? that they are completely wasting their time?? or do they blithely wander around truely believing that unless they take part in this action the door will not open and the twenty or so people also waiting to get on board would just stand there looking at an unopened door???? What a wonderful sense of self importance they must have!!
