If you catch your mistake(s) before the Grammar Nazis do, they are disqualified from correcting it. If they do, you are thus allowed to attack them with "Extreme Prejudice" if you're so inclined. Mostly if that happens I just say "Ummmmm...your way late, I'm way past that!" That's the rules I made up for this kind of situation, because, man, do I make a lot of them!! Lol. People barely bother me about that anymore! Ha ha! :)
