As editor of a newspaper, no one is more cautious than me when it comes to making fun of someone's typos. That's because it's only a matter of time before the typo is mine and I'm the one shaking my head wondering how I missed it.If you think catching all the errors in a one-page office memo is tough, try finding all the mistakes in an edition of the newspaper with some 20,000 words. If you're 99.9 percent accurate, you'll still miss 20 errors.That little bit of math aside, I can't resist laughing at President Donald Trump for his now-infamous tweet made after midnight where he uses the word "convfefe."
