Women: how assertive are you? Men: how do you respond to assertive women?

I am just watching a psychologist talking about the notion that girls are raised to be “nice girls” but as adults, in order to reach our goals, we need to move away from some of those rules and become assertive. Are you assertive and in what ways do you demonstrate your assertiveness? Or do you tend to come across as aggressive or passive?

And men, can you explain how well you relate to assertive women and provide examples of interactions where women have got being assertive right or totally wrong (and have been either too passive or aggressive)?
