The annual holiday, "what are we doing for our family get-together" silent text thread.
I see my siblings and their kids often enough, but its the other two that don't because of kids and schedules, but somehow they still expect me to attend for the stuffing our faces again and sitting around watching netflix. Not doing anything meaningful again.
Also pointing this out makes me the jerk, as does saying "you guys communicate and figure something out, I end up doing it every year and am done"
