Two little sisters were arguing over an orange, "Give it to me, I want this orange, it's mine" shouted the first girl."And I want this orange too, I need it right now," cried the other girl. The mother came in to the kitchen, took a knife and cut the orange in two halves. She gave each little girl one half. The first girl peeled her half, threw away the skin, and ate the inside. The second girl also peeled her half of the orange, but threw away the inside, and put the skin aside to dry. She wanted to make some jam out of the orange. This scenario illustrates how difficult family relationships can be. Which of the following options should the two sisters work on to improve their relationship? a. listening to their mother b. compromising with each other c. communicating their demands d. all of the above (I've tried d and c and they didn't work, so I really just want to see if others think it is b as well)
