First, find out why? Do they miss you, or do you have family obligations that require you to be home? Is the obligation that you have to help care for relatives or is there a job you have to go to? Once you know why they want you there, it’s easier to discuss the matter with them. If the issue is financial, talk about getting a job near campus. If it’s that you have to help care for a young child or a sick or elderly relative, try and work out a system where you alternate weekends. If the issue is merely that they will miss you, try and include them in what’s going on in your life. Invite them to campus so they can get a glimpses of what you are doing at school. reassure them they are not losing a child, but gaining a better educated adult.
