Family Etiquette Questions.
My mother-in-law lives near us. My husband's brother, wife, and family come often to visit, as do my sister-in-law and her family. Most recently my mother-in-law talked about going to a theme park when my sister-in-law and her family come to town. I told her about a special rate they were having for the park. She told me that the rate was great and that she would like to buy park admission for her and her husband, and my sister-in-laws family. She specifically excluded my son (her grandson), my husband, and I.
This isn't the first time she has excluded us. She often pays for everyone else when the bill comes, like at a restaurant, and does not include our family. I feel a little offended by this as I would not do this to my own family. It's not like we can't afford it, I just feel like we do a lot for her and she's always taking from us, but never is giving and then she treats like we're strangers when the other siblings are around.
Is this a selfish attitude on my part? Am I wrong to feel this way? How should I handle it? Should I just not go with them?
