We introduce a process, that we call shearing, which for any given normal Loewner chain produces a normal Loewner chain made of shears automorphisms. As an application, and in stringent contrast to the one-dimensional case, we prove the existence of a starlike bounded function in the class \(S^0\) of the ball \(\mathbb B^2\) (in fact the restriction of a shear automorphism of \(\mathbb C^2\) ) which is a support point for a linear continuous functional.
