Although you don’t want to provoke an angry confrontation, you also don’t need to be a passive-aggressive person’s punching bag. Passive aggression can be very damaging and a form of abuse. It’s your right to set boundaries.  One of the biggest mistakes people make is to be way too lenient. Once you give in to passive-aggressive behavior, you lose your options. This is, at its root, a power struggle. You can remain positive and calm, while still being strong and firm about how much you are willing to take. Follow through on the limits you set. Make it clear that you won't tolerate being mistreated. If a person is constantly late and it bothers you, make it clear to the person that next time she is late meeting you for a movie, you're just going to go in without her. That’s a way of saying you’re not going to pay the price for his or her behavior. The best way to deal with this type of anger is to detect any changes as soon as possible. The best way to do this is to get to the root of the anger.  If this person is one who doesn't typically show anger, then talk to someone who knows the person well enough to tell what angers him or her, and what subtle signs that the person may give when angry. Dig deeply, and honestly assess what might be driving the passive aggression. Passive-aggressive behavior is usually a symptom of another cause. There's aggressive communication, there's passive communication, and there's passive-aggressive communication. None of these is as effective as assertive communication.  Assertive communication means being assertive and nonreactive, yet respectful. Show confidence, be collaborative, and express that you want to solve the problem in a way that works for both people.  It's also important to listen and not inject accusations or blame into the conversation. Consider the other person’s point-of-view, and acknowledge it. Validate their feelings, even if you think they are wrong. If a person is passive-aggressive towards you on a regular basis, it is perfectly reasonable to avoid that...
