<human>: So my stepson and wife were out of town for Christmas. They recently came back and we has our Christmas as a family. It's now time to go to my parent's house to open the gifts they purchased for him, as well as the gifts my siblings got for him. 

My mother called and informed me that she had purchased more gifts for my niece to open so she didn't have to sit and watch him open presents, as that's not fair. Why should my stepson have "two Christmas's and she not?"

 I had to do this vary thing during Christmas- as my family wasn't here. I was graceful and I sat there. I'm pretty annoyed and hurt as I wanted this to be about my stepson. He's been gone and I missed him.

I love him like my own, and don't plan on having any biological children of my own. I have known my stepson almost his whole life. My niece is my mother's only grandchild and I suspected she favored him, but as she becomes older it's clearer and clearer. 

I want to say something, but I don't know what. I don't know how to handle situations like this in the future. I don't want my stepson to be hurt in the future as well. For example, during his birthday party what if they decide to do this as well? Should I let it go? Even if I should let it go- would you be mad? I feel like even though I should let it go my anger is justified and I just want to know if that's true or I'M the one being a brat.

Can you provide a brief overview of the text?
<bot>: Mother doesn't want her grandchild to 'go without presents' so she's buying her more to open. I'm annoyed but I'm not sure if I should just stuff it and move on.
