What to say to someone you haven't seen in 20 years?

When reconnecting with someone after 20 years, a warm and friendly approach works best. You might say, "It's been so long! How have you been?" or "I can't believe it's been two decades since we last saw each other!" Expressing genuine curiOSity about their life can help bridge the gap and reignite the conversation. Sharing a fond memory from the past can also be a great icebreaker.
