Which moment featuring Meredith has been your least Favorit over the past seven seasons of Grey's Anatomy?

Probably the scene in season three when we all new Meredith was going to pick Derek and then Derek walked away from her it was such a shame. oder the scene at the end of season three when Meredith goes all weird with Derek and won't reply to him when he says he loves her etc! I just wanted to hit her for that!
