He was keeping a detailed diary of everything Fritz said in that first year largely so as to take notes and limit his chances of saying the wrong thing.

That is amazing and while I am sure it must have been stressful, I kind of love that detail. Holy cow.

Both Fritz and Wilhelmine report being underfed by FW. Not just poor quality food, but not nearly enough food at times.

Oh right. Ugh. The kind of awful thing about Wilhelmine's memoirs is that FW does so much crap that I sometimes don't even remember some of it, because it's overshadowed by the worse crap. But... yeah.
