Of all the grammar mistakes made by Yahoo! writers and editors, this is probably one of the worst because it’s in the first word of the first sentence of the first paragraph. And it’s soooo obviously wrong:
I don’t know anyone, much less a professional writer, who would say that, much less write that. The Yahoo! Parenting writer needs to go back to second grade or start hanging out with people who speak correct English.
You, me, and the rest of the English-speaking world know that the correct pronoun is I, not me. And if it sounds awkward as the first word that’s because it shouldn’t be the first word. The pronoun I should come second in the compound subject: My 7-year-old son Jack and I.
