You must also understand her temperament in order to know how to adjust. Accept and value each other's differences wholeheartedly.
Create a bond with her that would make her your best friend. This desire should begin with you.
Despite this, your relationship with her and your treatment of her should not change. Keeping in touch is a great way to show her how much you value her.
The difficult times you have with her are an opportunity to strengthen your relationship and eventually draw you closer.
Even though you are blood relatives and belong to the same family, you should exercise caution when expressing candid opinions. To summarise, avoid overfamiliarity.
We sometimes overlook their admirable characteristics and behaviours. Because you see your sister's strengths and weaknesses every day, focusing on her flaws is usually easier.
To show your sister respect, treat her the way you want to be treated in return. Recognize your limitations and give her space when she requires it.
Try doing physical exercise, cooking, hiking, a movie marathon, travelling to other places, participating in a sport or game, and so on.
Remember that you are not supposed to compete with her. As a caring sister, you should rejoice with her in her victories and weep with her in her losses.
Aside from that, your simple affectionate gestures can already mean a lot. It's because your touch and hugs are more powerful than your words.
