Is AUTHOR wrong in the post ? POST : Alright, so some backstory. About 5 days ago, my mother was given surgery to remove a vaginal cyst the size of a football, which may have been benign cancer, but there was an incision that cut across her stomach area to remove the cyst. This incision made it impossible to get up or lay down from or to a resting state without help.

My stepfather had taken a week worth of vacation time to visit her, and instructed me on how to take care of her. His vacation time ends today, and I am the only one capable of taking care of her.

My sister recently left for a friend’s house and has not come back after a dispute, so she would be the only possible candidate to take care of her if I left.

I joined the Ski/Snowboard club of my school to be more active, and we needed to pay hundreds of dollars for all the equipment, rentals, and transportation.

The Ski trip is 2/7/19, and going on it means she will be alone for eight hours.

tl;dr: Mother recently had surgery, cannot properly take care of herself alone, not many viable people to help, ski trip upcoming and going means she will be alone for hours on end.

So, WIBTA if I left my mother to go on a ski trip?
