This aspect smoothes over any other more troubling communication issues that exist between you, because it creates a feeling of intuitive understanding and positive energy. Your partner is able to communicate themselves well to you, and they'll feel genuinely heard by you. When two people have an emotional bond as close as yours, they tend to affect each other on an emotional level in both good ways and bad -- meaning, when one is feeling down, the other is dragged down too, and so on.
The good thing between you is that, though you do share that intimate bond, you aren't likely to pull each other down. Though the emotional link is close, you still maintain your own separate emotional life, so when your partner is feeling gloomy and pessimistic, you are still able to see the sunshine. Better yet, you are able to boost their spirits! This is a gift you give to each other, so it's not likely that one of you takes the role of cheerleader more often than is fair. In general, you both take an optimistic outlook due to the positive energy that flows between you, and you have some wonderful conversations -- ones that aren't necessarily always be verbal. Your intuitive connection fills in the gaps!
