Books with title Mary Poppins in the Park

Have you ever run across that one unique individual who, for some unknown reason, seemed to have a grudge against you? Did they find ever more inventive and devious ways to annoy, bother or otherwise irritate you? Maybe you thought of revenge. Maybe you took the high road and ignored their persistent slights. Maybe you just seethed silently and reveled in every one of their missteps. This is the story of two such people, told in a very Suessian style, that hits home and the funny bone.
