Those who wish to sound well-educated and believe supposed "correct English" takes priority over effective (and/or aurally pleasing) communication, please note that there are plenty of people who think you sound pretentious/snobby/hypercorrective/anal. So while you may think you are showing off your education, you are instead revealing a tedious low-minded obsession with superficial shibboleths, like a morbidly obese trailer mom submitting her pre-K daughter to beauty pageants.
