Help me study for my Psychology class. I’m stuck and don’t understand.

Interview another couple who have been together for a long period of time. Explain to them (in your own words) how couples develop a division of labor with regard to memory, where each partner knows certain things (e.g., where all the items in the kitchen go), as well as what kinds of information the other partner has in his/her memory. Explore how they arrived at this “division of memory,” how well they think it works, and how it contributes to their relationship.

Please share some highlights from your case study.
