The Mad Hatter did not give any attention to Mr Angry Face, but he did pay this and that because he owed it. It was an internal matter of that sort of thing. He noticed two beautiful young ladies sitting in front of him who were engaging in conversation. How rude not to be invited he thought, they won't mind if I but in. 

"Why hello there, dearies, how wonderful to meet me!" He said giving them both a hand shake. 

"So whats your names?" he said with a smile.
