Our younger child watches TV when she gets home from school, while our teen is on the internet. It is always hard to make them come to the table. They will typically grab a plate and go on with their viewing/browsing.

This is a tough one that most of us have to deal with. Communication is key.

They may grumble a bit, but inside, they're probably as grateful for the time together as you are.
