Is NOBODY wrong in the post ? POST : Below is a list of the evidence that my in-laws favour their daughter (23) over their son (29):

1. When he left for school, they immediately turned his bedroom into a study for his sister. 
2. They sent her to a private high school and him to a public high school. 
3. They have many pictures of her up around the house including one professional family photo of only her and the parents. He was not even at the photo shoot. 
4. They always tell her information about family health and forget to tell us. 
5. She knows all of the family financial information and account passwords, etc. He knows nothing. 
6. They paid for most of her wedding and gave us the money to pay for ingredients for the cake. 
7. One Christmas I asked them to split the cost of an iPad 3 ways with his parents, my parents, and me. They did. They did not get him an additional gift. They bought her an iPad and a trip out West for a week (by plane). 
8. They take her on vacations with them and have never even invited us. 
9. He had to work through high school and college and pay his way but she gets all kinds of help and barely works. 

She is bright. She’s going to work in the medical field and he is too. He has a degree in psych and works with people with mental illness and addictions. His parents just treat her differently for some reason and it’s not right. My husband says I should just let it go to keep the peace and he doesn’t feel it will help anything, but I am just so angry about it and have come to resent them.
