Monday in the Park with Robert

Robert has the same work routine every day. Wakes up at 7:30 AM, gets ready for work, leaves his house at 8:30 AM, arrives at his desk job at 9:00 AM, and works until it is his lunch at 12:00 PM. Then he walks to the nearby park, sits at a bench and enjoys his half hour lunch and gets back exactly on the dot and resumes work until 5 pm. One day Robert finds a woman that could disorientate his schedule, does he help her or continue with his flow?
