A lot of Halloween costumes can be considered offensive to multiple cultures. say if an American wore a Pocahontas costume it would be offensive to native americans.
The tone starts starts out lonely, like the author says, and turns to cheerful, as the author sees the daffodils.
The words "Fluttering" and "dancing" helped you determine that the author is happy, and the words "wandering" and "lonely" help you determine the beginning tone.
Hope this helps ya
