AITA for exposing my mom after she hugged me only to hand me my sister's tuition bill?

The first real hug my mother had given me in years came with Ava’s college invoice folded under her other arm. She smiled like she had missed me, waited until the whole family was watching, then slid the bill next to my plate and said, “This is your chance to finally act like a son.” By dessert, she had shoved me into a cabinet. By midnight, her version of our family story was dead. ---------------🐼Panda Tales🐼--------------- #reddit #stories #redditstories
