The Missing Subject Isn't Cute — It's a Legal Liability

I keep seeing "went to the store" or "finished the report" in written English, and nobody blinks. In spoken Korean, dropping the subject is natural; in written English, it is a void where the reader must guess who acted. Draft an email like that and the client will assume you meant them, not your colleague. Correct once, and the habit stays corrected — that is the point of precision, not pedantry.
