To determine the overall tone of the passage "My Friday Evening," I'd need to know more about the content and specific language used in the passage. However, if the passage describes a joyous or fun experience, the tone might be lighthearted or playful. If it conveys a sense of seriousness or sincerity, then earnest could be the tone.
Without more context, it’s difficult to choose definitively. If you can provide details or summarize the passage, I'd be able to give you a more accurate assessment!
