While I am happy to tell you that I think the nicest thing I have ever done (and continue to do) is to not sing in public, casting around for something to say about today’s prompt, I came across Thank you, Masked Man, and couldn’t agree more with what Martha Ann says (thank you masked woman).
For me the essence of being nice, in the context of this prompt, is just be nice for God’s sake, don’t go looking for kudos as well. As Martha pointed out, recent Daily Prompts have been, well, an invitation for “selfies” – and although writing about a subject you know well (and hopefully, we all do know ourselves well), is good practice, blogging about yourself day after day is not going to be all that riveting for your readers. However, you could challenge yourself more by responding to the prompt with something unexpected, or at least a less obvious response.
Something to think about – saying you have done something “nice” may not be the best admission you could make about yourself. Here are some definitions as found in the Online Etymology Dictionary:
“In many examples from the 16th and 17th centuries it is difficult to say in what particular sense the writer intended it to be taken.” [OED]
By 1926, it was pronounced “too great a favorite with the ladies, who have charmed out of it all its individuality and converted it into a mere diffuser of vague and mild agreeableness.” [Fowler]
“I am sure,” cried Catherine, “I did not mean to say anything wrong; but it is a nice book, and why should I not call it so?”
“Very true,” said Henry, “and this is a very nice day, and we are taking a very nice walk; and you are two very nice young ladies. Oh! It is a very nice word indeed! It does for everything.” [Jane Austen, “Northanger Abbey,” 1803]
