One example that comes to mind is that some women will actually cry at work. For males that aren't used it, this can be a major WTF moment and they'll take it as a major sign of instability or irrationality. In fact, it is just a coping mechanism and it does not have the same meaning or weight as it would for a man to cry.
In other words, if a woman cries at work, the equivalent behavior for man would be an aggressive retort or a temporary withdrawl from the situation. For women, this might seem like the man is a being a jerk-- but, like crying, it is coping mechanism.
