I'm going to tell my mom I'm not coming for thanksgiving
What do you plan to do instead on Thanksgiving?
I want to spend some time with my friends on that day.
When you know you're going to do your own thing, let everyone know right away. If you've come to the conclusion you just don't wanna be there, stick to your guns.
Yeah that sounds like a good plan.
They will understand if you are honest about it. And make sure to let them know ahead of time so they can adjust the place settings before.
