"Well that's... difficult. There are people I'd trust with the job of feeding you but I don't feel I have the authority to ask you to trust them on my say-so. On the other hand I am also very reluctant to take you along when I go to do my job, which involves extensive contact with other mortals and with secrets I am not authorized to dispense to you. And I could request a longer leave so I could stay here and feed you, but - it's not trivial, my job. There are not that many people with my qualifications, and some people are alive today who wouldn't be if I hadn't got the right thing to the right place at the right time."
