No, just completely puzzled as to our conversation.

I'm inclined to believe Yasu, so this would be between Yasu and you then :-)

Nobody asked you to drag anything out. I asked two questions to Yasu, one of which he answered, while choosing not to answer the other one (for whatever reason). Anything beyond this has been unnecessary in my opinion.

I can't say I'm too depressed about that ;-)
