To all of those people who mistakenly think it doesn't:
Spelling really does matter. Do you know why? Because every time I ask one of the kids I'm tutoring whether they know the definition of "allusion," and then write it down for them just to be extra helpful, they tell me that it's something you think you see that isn't really there. For "anecdote," I either get "ana-what?" or "the cure if you get poisoned."
