AITA for laughing in my mother's friends face when she told me to 'go to my room'?

She arrived at the house of a woman she hadn’t spoken to in years, burdened with the weight of unresolved pain and silent resentment. The walls echoed with memories of abandonment and broken ties, as she only sought to retrieve a simple doc*ment—a symbol of her past—yet was met with the same old chaos and manipulation that had driven her away.

In that moment, the fragile threads of family fractured further, as her mother’s sudden emergency became just another excuse to disrupt her life and demand sacrifices she was no longer willing to give. The bitterness of lost years and denied connection simmered beneath her refusal, a quiet yet fierce stand against the endless cycle of neglect and control.
