I am very upset to have had a big row with my sister. She told me I had a chip on my shoulder and she was reluctant ever to phone me! The funny thing is, I feel exactly the same way about her! What does the future hold for our sisterly relationship.
I do not need a compatibility chart to show me that you should fix this misunderstanding with your sister, and fix it now.
When you have a relationship of any kind with another person, you mirror each other. What you see is what they see. You hear what they hear. What you feel is the same as what they feel. When you look at another person with a smile on your face, generally that person will smile back. It only takes one barbed comment; perhaps a misunderstanding, for that smile to turn into a scowl and then there are two faces scowling at each other. This is not a theory; it is a fact and you have proved this by saying that you both thought the same about each other.
Speak to your sister calmly and honestly and fix this before it goes on any longer. Sisters are precious. Hold on to her.
