How are there bright and dark fringes in single slit diffraction when it does not interfere with anything?

When the wave meets the sides of the slit the waves direction changes slightly so then some parts of the wave head in slightly different direction, these waves create the other bright fringes but they are not very intense because so little of the wave is diffracted :)
