I am returning to work after I graduate in December.  I have spent the last 8 years at home raising my children and caring for my family.  I have been getting this same question over and over again "Why would you take so much time away from work?"  The response to care for my family seems like a joke, can someone give me a better statement to give during an interview to make this answer not seem so meaningless.  Thank you.
