Can anyone tell me the meaning of the poem 'original sin on the sussex coast' by John Betjeman?

Answer 1

"Original sin" is a concept of some Christian denominations that you are born with sin because you are a descendant of Adam and Eve. As for the Sussex Coast, could it possibly be some reference to water and the breaking of water when one is born?

Answer 2

Sounds to me like a bunch of spoiled rich kids ("well-dress’d, well-born, well-fed, even at nine a perfect gentleman") beating the crap out of another boy. And no one really noticing what their "nice" young boys are doing...("Mum, the Persil-user, still believe that there’s no Devil and that youth is bliss? ")
