When it comes time to gather family & friends over the holidays, take some time to talk and play games the old-fashioned way...you know, before electronic gadgets. I am not anti-electronics, heaven knows plenty of them exist in my home. But I am very PRO-communication. Communication skills are hard-won, hard-earned and learned even in the best situations.
So why not practice listening, sharing, and getting to know those around you better while relaxing with some games? We often utilize these activities in psychotherapy (with children or teens in particular), but they have helped many families "break the ice" after forgetting how to connect.
