How can I get along better with my Sister??

I think it's a matter of give and take, trying to keep the others' perspective in mind. As a woman myself, albeit a woman who's never had issues with her brother, I can tell you that I don't like men who think they have all of the answers. Try to remember to ask for her thoughts and feelings, and try to actually listen. If she will try to do the same then you should start to make some progress.

Dear, it was the case with me also. Now I worked out this problem. I just have subjugated my ego for her. The things of her which I can accept I simply accept otherwise I humbly apologise to her. I make her relaised that if I said something that is not to hurt herr sentiments emotions and so can you do. I try to be as much to the point as I can. I do not mingle too much with her. But whenever she wants me, I try to help her out and spent my time with her with full vigor. Hope it would be of some help to you. Regards
