I honestly don't remember what I answered for Frodo... listed a couple of "compassionate" things pretty high, I think. Sorry!
There is another model I like that uses the Johari Window for showing your knowledge...
I - Things you know you know
II - Things you don't know you know
III - Things you know you don't know
IV - Things you don't even know you don't know
In this case, IV is the pane that you hope is not larger than the others!
