what is the theme of this story When Katie Clean invited Messy Missy to her house to work on their biology project, she had no idea what a visit from Messy Missy entailed. First of all, it was raining and Messy Missy neither bothered to take her boots off nor thoroughly wiped them on the doormat. Then Messy Missy ate a bag of hot chips on Katie Clean’s white bedspread without asking. Messy Missy is a sloppy eater too, so hot chip powder got all over the bedspread. Katie Clean tried to be polite and ignore Messy Missy’s sloppy behavior. But then Messy Missy threw her chip wrapper on the floor. Offended, Katie Clean pretended that she was sick and asked Messy Missy to leave. The next day Katie Clean asked the teacher if she could work by herself. After Katie explained the situation, the teacher allowed Katie to work alone. Messy Missy almost finished the assignment alone, but she spilled grape soda all over it and quit.

if interdependence implies a two-way dependence, and if each partner is equally dependent on the other for success, then there is an equal commitment to the making the partnership successful. the advantage is sustainability of the relationship, the disadvantage is that decisions are "democratic" and therefore may take longer to reach and more likely to be a compromise (which is not always the best solution). as the interdependence moves away from equality, the decisions become more influenced by the more independent partner. in the extreme the relationship becomes more dictatorial and more like "master-slave". generally the relationship has less commitment in both directions and is more likely to be temporary.

if one generalizes (and one shouldn't), equity partnerships, which is probably what is implied by interdependence, can be slow to progress or change but durable. the extreme alternative, independent-dependent partnerships tend to be efficient but more fragile.

hope this but you will have to site your own evidence. : )
