In "Sunshine" by Robin McKinley, the narrative highlights the challenges and demands of running a busy catering business. The protagonist finds herself consumed by the immediate responsibilities of serving large groups of tourists, which leaves little room for planning ahead or reflecting on personal events, such as an upcoming birthday party. This emphasizes the hectic nature of her work life, where daily tasks overshadow future commitments.

The quote reflects a broader theme of juggling multiple obligations and the struggle between short-term responsibilities and long-term planning. The character’s focus on the present situation illustrates how overwhelming business demands can hinder personal life, creating a sense of chaos and urgency as she navigates her daily routines.
