Because that's when you tend to snap at people around you and every little thing that you disliked about the other person is suddenly thrown in his face in the nastiest of way.

Except that it's not and in those first few months you really need someone you trust completely, someone who won't get hurt or pull away. You aren't it, G. You two are still on shaky grounds. It's not going to end well."
