I haven't reread my materials at all... But I got a call with a fellowship offer today, and they asked for a "clean" copy of my SOP. Turns out, I left a comment on it that said something like "should I add a quotation here?" Excellent work, really my finest hour. Somehow they still accepted me and do not think I am a complete idiot, and luckily that was the only one that had a comment on it still.
