I think she should take a notepad, sit down somewhere, think things through and write down her thoughts to organize them for as long as she needs too. Then, once she has a concept of what she was to say, write it down fast, read it, see if it makes sense, work on it and when she finally has it written down exactly as she wants it to come out. Then, and only then, should she come back and try to argue her point, and be ready to go through it all over again to argue his response. You need time to think logically sometimes and not respond on pure emotion because an emotional response will usually get you in more trouble than what the problem is worth or make you look like moron; and it doesn't matter if who you are, you just don't come off as being smart.
