"Rule" refers to the 196 community's rule that if you stop in, you must make a post before you leave. People post totally random things that are often quite funny and they put the word "rule" in the title. Sometimes that's all they put in the title.

My kid is learning to drive and I wanted to rent/get ahold of a manual to teach that too, but nothing doing. You can't find one to rent and I'm not buying a whole car for a few weeks' training.
