I'd like to make a list of commonly known "rules" that people have learned and follow, but are in fact not rules at all, and by following them people are led astray.
The best example of what I'm looking for is a grammar rule that many of us were taught as kids, which says that it is correct to say "Steve and I
," not "Steve and me
" or "me and Steve." It is improper to say, for example, "Steve and me are going to the pool," but presumably it's this "rule" that makes a lot of people say things like, "Would you like to go to the pool with Steve and I?"
I'm not just looking for grammar rules. It could be programming, driving, etiquette, or anything else that people regularly do improperly because they understand it to be "the rule." To be clear, I'm not looking for things that people just don't realize they're doing incorrectly, or that there's a better way of doing. That was covered thoroughly in the You were doing it wrong
AskMe thread. I'm looking for specific examples of actual, known "rules" that are flawed, or just commonly misunderstood, but people follow anyway because they believe it means they're doing it right.
Thanks for your help.
