I'm somewhere between LFA's and CG's answer....the first part, definitly. Don't offer more info than is necessary.
But as for taking half the china...half a dinner set isn't much use to either party. Right?
so would a better division be one of you gets all the china, one gets all the crystal, that sort of thing?
Unless you think X is just not the sort to ever care that he has any nice china or crystal--in which case, you take it all.
If anyone agrees with me that half a dinner set isn't much use, than LFA should take whichever thing she most likes...the china or the crystal or the cookware.
