<p><b>DEAR ABBY:</b> I recently hosted a family gathering that included my adult cousin and his wife, who live locally, and my son, daughter-in-law and their son, who traveled from Georgia to Pennsylvania to visit.</p><p>Since my son and family rarely see relatives, I thought it would be great to get everyone together. At the gathering, my son barely acknowledged our cousins. He and his wife didn't participate in the conversation — instead, they pulled out their phones and generally looked bored and anxious for the company to leave.
