This is an interesting statement.
It makes me think about the whole idea guys have that they have to change for a woman. Well, yeah, in some ways. This happens sometimes a guy acts differently around a chick until he snags her, then he "reverts" back to how he "is" and gets all huffy when the woman is wondering wtf just happened. And sometimes it happens because it really is just time to grow up. And who doesn't want change? What is the option? Stagnation? Not appealing.
