What is the most upsetting experience you’ve had with your sibling?

Recalling my interactions with my sibling, the most upsetting experience was when they broke a sentimental gift given to me by a close friend. It wasn’t just the material loss that was frustrating, but also the careless disregard for something that held emotional value to me. This incident caused tension between us for a while and required a lot of communication to address underlying issues, like the need for respecting each other’s belongings and understanding the emotional significance they might have. It became a learning experience that eventually brought us closer, encouraging a more respectful and empathetic relationship moving forward.
