You can't always explain why some conversations flow and others grind. But the traits that make someone easy to talk to are learnable.
They respond to the details. They ask follow-ups. They don't redirect to themselves after every story you tell.
Ease of conversation requires safety. When someone signals they won't judge you for saying the wrong thing, you relax instantly.
Easy people match your pace. They're warm but not intense. Present but not consuming. They fit.
Listen more carefully, judge less, respond to details — these habits change how every conversation feels to the person across from you.
