And yes-I’m an unapologetic grammar Nazi...
So am I, though perhaps not as sheltered as some. Homeschooled and fluent in French, I hear more "wala" than "voila" from my contemporaries (nearly all of them, college graduates). They can't spell, they split infinitives, and they'll shamelessly use objective case pronouns as subjects. "I'm like" has replaced "I said."
These atrocities are commonplace nowadays. Sometimes when triggered I turn to a facebook page titled, "The Grammar Police." It helps.
