remember von's famed german glass tea set? on which there is a standing (and definitely not silent) contract that breakage = malicious intent = deserving of disembowelment?

me: *crossly* the trouble with stuff like that!
me: you "given" it to me but we all know it's sort of yours still
me: so if i break it accidentally tomorrow [while moving]
me: you'll go on about it!
me: and how useless i am!
von: *magnaminously* i abrogate my own rights to go on about breakage
me: oh!
von: just don't you go breaking the damn thing
me: IDIOT
von: heh
