In the season 6 promo does it look like House is flicking a letter away when he is sitting on the bench with his hat on? Possible note from Cuddy??

OMG YES!!!! it does oder maybe its TO cuddy bcuz maybe hes embarrassed about the hallucination and he doesn't want to talk with her on the phone so he writes a letter then its not good so he throws it away. oder hes trying to tell her that he loves him!!! that would be awesome

No, it looks to me like a card.
But we can hope
