In good friendships one is used to a certain kind of communication. Usually very few if any topics are off limits. You share what you think, who you are, what you experienced, what you want and hope for. Then the communication changes and you don't share anything serious anymore and you just talk about the weather. You can't really pinpoint the problem and you are not sure what has happened, yet something has shifted, moved out of its place. You would like it to go back, but you don't know if it ever will, since you are not certain about the core of the problem or if there even is one. With a lot of issues, it can be solved by talking it out, but with some, talking won't help. Sometimes things go back to normal, but what if they don't?
