If I say I'm angry, that means listen to what I have to say. Don't provide feedback. If I'm depressed, then provide motivating helpful feedback. If I'm angry, I just want to talk to hear myself talk and get it off my chest. Even if what you're saying is completely valid, chances are that I've already thought of it, and you saying it doesn't really help me out.
Not a slight at anyone in particular, but this is definetely a useful code for the future.
