A growing trend online and offline is people going "no contact" with friends or family. A Cornell University study found 27 percent of American adults are estranged from at least one family member.

While some people cut ties to escape abuse or political conflicts, others seek to rebuild relationships later. Here are tips for reconnecting:

• Let go of the past: Avoid dwelling on reasons; complete understanding might never come.

• Listen openly: Hear that person's side without defending yourself and acknowledge their frustration.

• Apologize: Apologies show strength and foster healing.

• Be your current self: Stay true to who you are now and avoid old family roles or dynamics.
