What if I don't want to do a bunch of errands for my family the last week before I move?
Why don't you want to help them?
I don't want to deal with them.
You should try to make time for your family. They need you and you should help family out.
This is going to be my last week here. I just want to relax and don't want to spend my valuable time with them.
Families support each other with help and assistance and you blowing off your family when they need you for errands is irresponsible. Take time out from your own concerns to think of what they need.
