Why does Noah Claypole look down on Oliver and treat him badly?

Noah is Mr. Sowerberry's apprentice. When he came to the Sowerberry's he was a charity case, and he was teased mercilously by the other boys. When Oliver arrives from the workhouse, Noah finally has someone from a social rung lower than his own to pick on.... and he does.

When Noah clapole was small he was treated very badly because he was very por but he was not born in the workhouse. When he became big he had found oliver. Now he could be rdue to oliver. Noah Claypole saI'd bad things about oliver's mother.
