No dairy of any kind per family
Clearly it means that they should refrain from writing in their journal until the family comes to terms with the memoir deal. (I expect it's a medical issue because of the death threats.)
Patient is lactose intolerant, and shouldn't be allowed a notebook to write down all the times kitchen staff give her milk anyway...
Because the patient will write down all the naughty bits about the family before death? Like the Duggars :)
What was it?
