What did Daddy say?

Michael told Ian that he remembered awhile ago that Ian said he was going to die after Christmas.  Ian was sure he did not say that, so the two of them tried to figure out what was said.  Ian brought it up at the dinner table to get my memory of the event.  Ian thought maybe he said that he was going to die from all the food he ate.  I suggested that maybe we talked about somebody that had died recently.  But neither of those thoughts really seemed to make sense.  But then it clicked in my brain and I remembered that Ian said he was going to DIET after Christmas!
