AITA for sending my family $1 for Christmas after they billed me $30K?

My family did not invite me to Christmas, but they did send me a bill for $30,000 for my sister’s new car. “Payment due before December 31,” it read, as if I were their personal line of credit. So I cut off all financial support and sent $1 each to my mom, my dad, and my sister with the same note: “Merry Christmas. This is what you deserve.” Just like that, they suddenly remembered I existed. ---------------🦦Otter Stories🦦--------------- #reddit #stories #redditstories
