Christmas eve

I'm terrified.
I've just learned that my sister's boyfriend is going to spend Christmas eve with us.
Why?
Why must I be with a complete stranger on the one and only night of the year, when our family is close together? I'm devastated. Why must he be here? If she loves him so much, why don't they celebrate Xmas together? Why must she drag him into my life too? Why can't I be alone with my mom and dad and sister, like we used to?
I hate that grinning idiot so much. I hate him for ruining everything.
Now, I'll try not to hate him. I don't want to hate anybody tonight. But it's so hard. The situation will be so awkward. Him sitting under the Christmas tree with us together. Like his part of the family. I'll never get used to this.
I wish so much that they'd finally move out to that new house my parents built for them. Even losing my sister like that would be easier for me than accepting him here.
I'll try to ignore him like I always do, not talk to him, don't even look at him...
Why doesn't my sister understand how I feel?

We're off to grandma in a few minutes. I'm writing this while pulling my pants...
After that it's church time. And after...

Merry Christmas for everybody!
