Deception is "Being human"? That's wrong. Maybe it's human error to forget to tell on the first, maybe even second date.
But come on. 9 god damn months? What was she trying to do? Manipulate the guy into loving her for something that she wasn't and then tell him and break his heart?
To say that behavior is the model for "Human", is inaccurate. A real human, a real woman is up front with the truth.
