Can I disinvite my sister to thanksgiving?
Why don't you want her to join in the holiday?
I hate her for insulting my friends.
Perhaps you could speak with her before the holiday. It's wrong to disinvite someone to an event. It's best tp practice patience with family members.
Why? I want to do it anyway. She's not my only family.
If you disinvite your family their will be an issue at all future holidays. Don't you think it is easiest in the long run to just have patience?
