If you thought that your use of vocabulary was impressive, then you miscalculated. Don’t fake it. Be genuine. An essay that says, for example, ‘I ain’t sure exactly how it happened, but by the time I was two years old, I was more attached to my old Grampy than a hound to a bone’ sounds a lot better, to me, than the kind of forced language you chose. I don’t mean to be insulting, and I know that this is important to you, but if you try to fake it and fool people, in my experience, the only one you fool is yourself. I get your points – but there are better ways to make them in your own voice. And, yes, don’t post your essays online if you have any thought you will ever actually use them. Cheerio!
