Characters can have barriers. Those carefully-constructed walls that are built deep inside their own heads, hiding certain parts of their being from others and even themselves. These barriers are not easy to break down. They need to be torn down, ripped apart, or – much more rarely – you need to ask for a glimpse. It is not easy to see through them. You will not immediately be the one exception to the rule; you’ll need to earn that title. Please keep this in mind.
