Explanation:
1) Aurora is upset because her roommate took an action that affected both without consulting her before, offended since she did not take into account the comments made while arranging the portraits, disappointed as she had other expectations with coexistence.
2) He could have spoken clearly with Liz, trying to reach an agreement avoiding the altercation and being more intentional with his words, since the comments may not have made clear the feelings of Aurora with respect to the portraits.
3) Emotional self-control to better meditate on their actions and the impact they would have in the long term and Social Skills to facilitate agreement with their roommate.
4) A conversation with her roommate to discuss the issue, where she could make sure that her partner was paying attention to her and in an environment that pleased both of them and to investigate the things that Liz would like, that would not bother Aurora, and if you can reach an agreement that benefits both because they could make a deal where each one contemplates the needs of the other
