My grandmother passed and there was a small graveside service. Just family - about 15 people (children, grandchildren, spouses). We were all supposed to meet at 11:30. I arrived at 11:25. Turns out, everyone else travelled to the cemetery together since they were all staying at the same hotel. They all arrived closer to 11 and decided to start without me. By the time I arrived (which was technically five minutes early from the scheduled time) the service had finished. AITA for not getting there earlier?
