My sister was due to come and stay for the weekend from abroad. She rang to invite herself and we said fine and agreed to come back from holiday early to meet her in the city. She rang to say she had missed her flight and would be a day late. We were already committed to leaving a day early so left anyway. The original plan was for her to meet us at our flat, probably arriving an hour or two before us. During the day she began texting as we journeyed home, eventually saying that unless we would drive 3 hours today to pick her up from the airport (through 2 cities) she was not coming. She had been due to get the train - 40 mins very comfortable and easy. She has accused me of not loving her and of depriving my children of the chance to see her. Alcohol maybe involved but what would you do? She didn't turn up and instead flew somewhere else - not sure where. Advice? She is a bit of a toddler and am inclined to ignore but she is alone and lonely so still feel sorry for her.
