- Start your meeting off by saying that you read the comments and understand and then explain the comments back to them in your own words to make sure you understand.
- Giving excuses about how much time you had to do something will never lead in a good way. Even if I didn't have enough time, it doesn't matter: the point is the writing wasn't good enough, not how much time I had. Complaining about it will take about 5 minutes and get you right back to the point you started: the writing wasn't good enough.
- Your supervisors want you to succeed. Thinking they're out to get you is stupid. You fail, they fail. You succeed, they succeed.
- Your supervisors are more intelligent than you and know what they're doing. You have never done a PhD, they have. They have supervised PhDs before (in most cases), you haven't. They know what you need to do to get through to the end: you don't.
Bottom line: argue when and only when it has the chance of a positive outcome. And trust your supervisors. Then again, I don't have my PhD yet and perhaps this might fail. We'll see.
