You find that you don't really communicate all that well. There's something lacking when you talk with each other -- awkward silences stunt the flow of conversation, and you might not always understand each other's jokes or points of view. You grow frustrated with each other, maybe just to a minor degree -- but it might be more significant than that, depending on other factors.
At base, what is going on between you is a disconnect in your individual focuses. You might be focusing on this person, but they might have trouble focusing on you -- and in fact, they might be focusing mainly on themselves. They aren't able to hear you because they're so focused on their own ideas, their own path in life. Thus, your needs end up flying over their head, unrecognized and unfulfilled. This isn't due to any kind of malice or even selfishness on their part; it's simply a basically benign disconnect that can be corrected if you both want it to be. You have to admit the fact that there's something not quite right between you, that the ways in which you two communicate tend to irritate both of you; and then you have to make the conscious effort to focus on each other, listen to what the other is saying and respond directly to that. The differences between you don't have to be threatening, or an insurmountable obstacle, but it takes some work to get past them.
