This is a debate. Debate – a debate. But not the usual argument, which by definition VI Dal is a "verbal contest, in which each party to refute the view of the enemy, defending his", and a formal dispute, that is, a dispute that has clearly defined framework, rules and restrictions. If a colleague can argue as long as there is free time to do it, then limit your formal debate controversy, especially over time. Each of you will have no more than 10 minutes to to express their point of view. Moreover, in ten minutes will be divided into several rounds (short three-minute intervals), during which you will need to have time to say what you think is the most important in the discussed question.

And if you're in the midst of the usual argument can afford to get carried away and go far enough away, there is exactly three minutes later you say "Stop!". Yes, you will be warned in advance the time-keeper (keeper of time), that all you have to say … then 1 minute 30 seconds … 15 seconds … then you are obliged to keep silent, to listen to … his opponent.

Now it is time he will prove his innocence. And you have no right to interrupt him. You listened Now listen to you. Listen and be prepared to ask questions about what he heard. If you want to downplay the significance of the arguments that your opponent will listen carefully, looking for weaknesses in his argument, catch him on an error in the proofs.
