Wow. Timr nailed it. It/They, You, I are very powerful context words. Next time you get in a real-life, face to face argument with someone and you want to escalate to shouting - start using you do this, you do that. I've overheard parents doing this with their kids many times. "Why don't you clean up your room?"

For bonus points, if you want to appear to be an elitist/snob to people you've just met say stuff like "This restaurant is the best" or "You should try this restaurant". I think this is called the God perspective (You passing judgement). (Always better to just make a statement of your opinion - "I like this place. Their food is different")
