If the world was a perfect place, everyone would be happy and have healthy relationships. This is generally not the way the world works, and a person must find a good partner to help them through life. Those who are with a patient and caring person will find their communications barriers breaking down naturally, but sometimes they may still need assistance. This is the best time to turn to a partner because this is the person who wants to stand by them no matter what the issue.
There are no guarantees in life, but a good partner still helps make life better. Most people will go through life with their own set of walls, but this does not mean they must close themselves off entirely. Choosing which walls to break down can be the best way to solve communications issues, and it gives their partner a chance to help them succeed.
