Secret: ...as in covert. As in hidden...camouflaged...not made public...disguised. Secrets need not be purposefully hidden...but are not made open unless...you know where to look,who to contact,what questions to ask. Some secrets are kept secret by structured anomolies,boards or committess. A secret is discriminatory in that it keeps 'the other' out. The sophistry of certain establishments of England is that it will always have its 'token' intake of 'other' so that it can raise it should it come under question.
Just watching the local news over years I noticed that when they reported on some local cricketer they always seemed to have a father in the game and that they had come from a 'certain schooling'...the more so than football. My comments are a generalization,of course,but I believe my premise holds some truth. Mark Steele cemented my prejudices over the games 'open-ness' when he detailed the 'funny trials and training cricket event' he inadvertently went to when playing truant from school. Its rather a sad story if and when you think about it.
