Final answer:
The speaker in the quote is the Miller, who is addressing little Hans and refuses to visit due to the inconvenience of snowy weather, revealing the Miller's selfish nature.
Step-by-step explanation:
The quotation 'There is no good in my going to see little Hans as long as the snow lasts' is from Oscar Wilde's story 'The Devoted Friend' which is part of his collection titled 'The Happy Prince and Other Tales'. The speaker of the line is the character named the Miller. The Miller is addressing his friend, little Hans.
The speaker refuses to visit little Hans because he considers the snowy weather to be too inconvenient for him to travel. This selfish rationale shows the Miller's true character, which is further explored through Wilde's examination of so-called 'friendship'. Within this storytelling context, the reasons given for actions often reveal deeper truths about the characters and themes of the narrative.
