Hi Seong Eun, 

Great job on completing your homework! It sounds like you have a thoughtful approach to considering other people's opinions while also staying true to your own beliefs. It's important to be open to different perspectives and sometimes that can even lead you to change your mind. It's also great that you stand up for your opinions, especially when you feel strongly about them. Keep balancing openness to others' ideas with your own convictions, and you'll continue to grow in understanding and confidence.
