It's possible that "It's Raining" is a declamation written by an individual or for a specific event, but without further context, it's impossible to determine the author.
To help me find the author, please provide:
* More context: Where did you encounter this declamation? Was it from a school assignment, a performance, or online?
* Any additional details: Do you remember any lines from the declamation? Are there any clues about the author or the time period it was written in?
With more information, I can try to identify the author or at least narrow down the possibilities.
