In a heartbreaking AITA post, a woman recounts her sister's cruelty towards her son during a medical emergency. The woman's nephew has always been claustrophobic, but her sister dismisses it as a phase. Recently, the boy was diagnosed with a mass in his brain and needed an MRI.
The sister failed to prepare him for the procedure and when he had a breakdown, she was incredibly mean to him and blamed him for wasting her time. The woman called out her sister's cruel behavior, but was called an AH for not understanding her struggle as a mother.
The post has received over 11k upvotes with many commenters agreeing that the sister's behavior was unacceptable. In an unexpected turn of events, the sister later called the woman, admitting she couldn't handle the situation and asking her to take care of her son.
