The first reason is because woman have a lot of emotions that can lead to anger. When boys get mad they fight each other.
The second reason is because sometimes when boy and girls have best friends , something can happen between both of them. For example, when your best friend talks behind you back you start arguing which can lead to violence.
Usually, the rule of thumb indicates the following:
1- Introduction
You say what you are trying to do with your text and how you are trying to accomplish it.
2- Body [1]
You introduce your topic and your argument [thesis] and introduce supporting detail.
3- Body [2]
You elaborate on the supporting detail.
4- Body [3]
You state what your opposing party believes regarding your argument, and refute it.
5- Conclusion
You reflect on what you have stated to accomplish the objective mentioned in the introduction, and how you have accomplished it.
The reason why you should not address a counterargument before/after where is suggested is because it's counterproductive to the purpose of the segments in the structure. If you do it in the second paragraph of your body, you didn't allow yourself space to support your thesis. Similarly, the introduction and conclusion paragraphs are not there for you to address anything, so doing so would be incoherent.
