I'm looking for a word that describes the following situations:
- A man and a woman are breaking up. Over the course of their relationship, their possessions have become intermingled: a box of his LPs at her place, a bottle of her shampoo at his. They agree to a series of events through which he takes back what's his and she hers.
- A company has two branches, one for accounts payable and one for accounts receivable. The company receives a large flow of correspondence pertaining to both. To sort this, they hire an uninitiated temp to determine which mail goes to which department. While in some cases the temp gets it right, in many cases each department receives mail which would better fall under the other's jurisdiction. Every week, they engage in a transfer where a courier from each department trades the other for the misdirected mail.
