I don't think I want to spend Thanksgiving with my family.
Why don't you want to spend Thanksgiving with your family?
Because my family is so annoying with the dinner. I have to deal with them for a whole day.
If you don't like spending time with your family then you should spend time with other people. We don't get to choose our family so it shouldn't be our responsibility to like those we were born around.
You're right. I'm going to let them know that I won't be attending this year.
I think it's good that you're being honest with your family. It also might be nice to see if any of your friends want to spend Thanksgiving together.
