Why my mei mei like that?

Dear User, thank you for reaching out. I can sense from your question that you are feeling confused and perhaps a little hurt by the actions of your younger sister, or "mei mei" in Chinese. It can be tough to understand why someone we care about behaves in a way that we don't expect or that we find difficult to deal with. From a Buddhist perspective, it is important to remember that all beings are inherently good at their core, but that we are all subject to the conditioning of our past experiences and our present environment. Your mei mei is likely acting in the way that she is because of a complex interplay of factors that are unique to her. It is not a reflection of your worth or value as a person. From a psychological perspective, it can be helpful to try and see things from your mei mei's point of view. Is she going through a difficult time at the moment? Is she struggling with something that she hasn't talked about? Is there something in your relationship that needs to be addressed? By attempting to understand where she is coming from, you may be able to gain some insight into her behaviour and what you can do to help. When it comes to coaching advice, I would suggest that you try to approach the situation with an open heart and mind. It can be tempting to become defensive or to lash out when we feel hurt or confused, but this is rarely helpful in the long run. Instead, try to initiate a conversation with your mei mei where you can both share your feelings and concerns in a non-judgmental way. Try to listen to her perspective without interrupting or becoming defensive, and then share your own feelings in a calm and respectful manner. By communicating openly and honestly, you may be able to find a way forward that works for both of you.
