Kari, nobody is saying Mish is right, personally I think they're both in the wrong for different reasons. Mish for the initial theft (may be a misunderstanding/confusion but don't know enough to judge), and Lego for bringing it up so late (may be no alternative motives but who the hell knows). I don't think either of them are going to get anything out of this post other than more hurt feelings and anger.
Apparantly the first time she did this never showed up on the FB, it is a good thing to see people outed, regardless of the reaction recieved.
