Have your siblings changed over the years or stayed the same?

Or do you find that you have changed?  Do you get along with them or have anything in common with them?

After a recent death in the family I just talked to my sister.  Her comments were almost, not cruel, but just not caring.  She says it was probably an inconvenience to my aunt that my cousin died.  Granted cus' and mom have not had a very close relationship over the years, but I would never doubt the love a mother has for her children (I'm not a mother) no matter what they have done.  I don't say anything to sis, because if I did it would get back (sis is like that -you tell her to keep something in confidence and she thinks its funny to go tell that person you just talked about what you just said).  I've kind of lost touch (emotional feelings) with her over the years.  I just don't know what happened to her (or is it me that changed?).  She has no sympathy for people in our own family, yet the people in her church (she joined a mormon church about 5 or 6 years ago), she'll be crying a flood of tears whenever something tragic hits their life.  She knows every intimate detail of all their bipolar lives (sis tells me they are all bipolar, not me), and she gets very emotional when telling me something horrible has happened to them.  Sis has a good heart, would do whatever she could for you and she and her husband have always been that way, but her emotions are just missing.  After talking with my aunt and hearing how upset she was and between her crying and me crying it was a hard conversation.  Aunt told me not to say anything to sis and now I know why.  Just hurts to know the same girl I grew up with, shared a bedroom with, lied in the snow making snow angels, lying under the weeping willow tree in the summer making pictures with the clouds and telling each other secrets, following her around everywhere always looking up to her, is not the same person now that I knew then.

I was just wondering if others have siblings they have grown away from.
