Hahaha... I think that this situation between siblings is a daily occurrence in most families... these days I saw a very nice post on Instagram, where a therapist talked about the importance of healing the relationship with siblings and realizing that in our lives they are great teachers, precisely because they teach us things like that, sharing or defending our own, setting limits, managing jealousy, envy, leadership, how to stand out, etc, etc... I agree with the therapist in all of that.
Every family member shows us and teaches us something, even in distance, or in absence...sorry they are no longer with you.

A hug for you 🤗
