My foster sister is in her 20's. She has moved out from my parents house. I am in my late 30's.
My foster sister will be graduating this year and she is upset because we haven't booked a holiday for her to celebrate her graduation. I didn't even know that this was a thing? My parents and I were going to take her out for dinner and give her a nice present.
Backstory- she has fallen out majorly with my sister. (I only have 1 biological sibling).
Every year we take a family holiday. Last summer I couldn't go because my husband's niece was getting married during that time.
My foster sister doesn't want to go on the holiday with my sister but she feels left out and gets very angry with the rest of us. My sister is the main person who books and organises the holiday. My parents are elderly.
Anyway so for Summer 2025, my sister has booked a holiday for my parents, her kids and for my family.
My foster sister is feeling left out. (I have tried many times to mediate but it ends in a huge slanging match and I don't have the energy for it)
My foster sister rang me- shouting and swearing that we shouldn't go on holiday when she is graduating. I don't know what to do....
If you got this far- thank you for reading.
