I saw my mom yesterday, and asked her if she had told my sister that I was studying again. After reading the comments here, I did wonder if they were putting on their conditional love, because they thought I "might be coming back."
My mom denied that she had said anything to my sister. She always acts like she doesn't talk about me to my other sisters... although I'm not sure what to believe sometimes.
I'm going to give my sister the benefit of the doubt, and just appreciate the moments that we had at the recital. Joking around with her, made it a lot more fun to sit through 2 hours of beginning orchestra music. ;)
My temptation is to SEIZE the moment, and try to reach out and pull my sister closer... but I am going to lay low, as I have been. I don't want her to think I am trying to attack her again... haha. Maybe this summer will give us a chance to reconnect with the kids at a neutral place.
