Communication is so important for all the important relationships in your life. For example, with a significant other or a teacher/professor. Good communication creates a good and strong relationship with people. Good communication creates a strong bond based off of trust. In relationships, you need that trust in order to thrive together. You can't have a strong relationship with anyone without trust or good communication. This applies to platonic relationships not just romantic ones. Communication is the most important thing to build a long-lasting relationship with anyone. In my opinion, it is the most important part about creating a relationship with someone because how are u supposed to trust someone who won't communicate their good and bad feelings to you?
