Let's take a look at how to strengthen the sister-sister relationship, and why it is such a great relationship to have in place.

In order to strengthen any relationship some effort has to be made. When it comes to the relationships in families, sometimes even greater efforts have to be made because it is so easy to be rude, mean, or our worst selves and expect forgiveness or understanding. We often treat those we are closest to the worst. If you want to strengthen your sister-sister relationship it is time to put an end to this. Start by working on the relationship the same way you would with any other non-related friend.

Next, spend time together. It is amazing how much fun you can have as sisters when you spend time together if it is not forced. Maybe growing up you did not particularly enjoy one another's company, but there is a good chance that that is partially because while you were growing up your parents forced you to spend time with one another. When you do it on your own terms, and of your own free will, it becomes far more enjoyable. You find that because you were brought up in the same home with the same values, you have plenty in common and that it is nice to share that with someone. Understanding comes naturally. Kinship, bonding, and the seeds of long lasting friendships are there, it is just up to you to give them the proper time and nourishment to grow.

You have to be thoughtful and considerate. It is far easier to hurt or offend a sister than another friend because you are intimately aware of their vulnerabilities. The thing about growing up with someone is that you are witness to much of the things that formed them, and you are privy to an insider look at their fears, insecurities, and self deprecations. This means that you have ammunition to hurt them. Anytime someone is close to you, and knows your fears, dreams, etc. they can use them to hurt you. For example, if you know your sister has always been insecure about her weight, and you make a fat-joke at her expense it is going to hurt her far more than someone who does not know her well making the same joke. She will feel as though you preyed on her insecurity. So, to strengthen your relationship you have to be extra considerate and thoughtful, as well as extra forgiving.

When it comes to your sister, always assume they mean the best, rather than the worst. Usually they do, and they just are not expressing themselves well.
