I heard this as an anecdote from a fellow who was in the military and thought it might be appreciated.

During Bootcamp there is a noticeable difference between men and women and how they interact with each other. The first few days for the men is rough whereas the women all seem to get along well. Then after a few weeks the men transition into working (and living) together well whereas the women are in disarray.

The reason this is all happening is because the men instinctively develop a social hierarchy. The first few days are spent jockeying for position but after a few weeks the men have "set" a hierarchy and know their place. They know who are the top dogs and they know who are most like them. This allows them to interact with each other more easily and they naturally follow whatever place they are put into.

In the women's camp they are all nice to each other from the get-go. They try and maintain this niceness but after a few weeks it is impossible to maintain. There is no hierarchy and there are no set places for each woman in the camp and this is not a sustainable model.

While it takes a relatively short time for the men to adjust to living with other men the women are incapable of making this transition. This is just one reason why increasing your own value and learning to recognize the value of others is important in life.
