I am not going to see my family that came from Colorado to visit us in Jersey.
Why wouldn't you want to go see them?
They are the most annoying people on this planet.
If you know they are in town then I don't think you should ignore them. You don't always get as many instances to see family as you would expect. If you have the time then you should go and see them.
I'm mad that I have to spend my time with them and I also hate my family.
I know it can be frustrating dealing with family, but it's best not to hate your family. If they came to visit you, it's good to spend at least some time with them. You do not have to hang out with them everyday they are visiting, but seeing them for at least a little bit will make them feel good!
