Answer:
Alice learns she is having a dinner party with guests whom she did not invite.
Step-by-step explanation:
Through the Looking-Glass, and What Alice Found There is a novel written by Lewis Carroll as the sequel to Alice's Adventures in Wonderland.
The detail that points to the theme that a person's path in life is already set is Alice learning that she is having a dinner party with guests whom she did not invite. We want to control all things that happen in our lives, but this detail shows us that sometimes it can't be like that. Some things are out of our control - they are already set and will happen no matter what our wishes are. That's why Alice has dinner with guests she didn't invite.
