Agreed ^... Joffrey is the only one Cersei knows she can't control. Cersei thinks she can control most people... but she lost Joffrey the day she slapped him in the Throne Room in front of the public. He has more power than her, and she knows he's not afraid of using it without his mother's consent anymore. Therefore Cersei is a bit wary around him when he speaks his mind, which is a change from how she acts around people like Tyrion, and it's very clear that she hates it. There's just nothing she can do about it. Having a king for a son is very difficult when you raised your son badly.
