When meeting someone for the first time, a lull in conversation can feel uncomfortable and awkward, suggesting that maybe this new acquaintance won’t become your new BFF anytime soon. Such a scenario reflects a generally simple rule of relationship initiation: when conversation flows easily between strangers, people tend to feel bonded with one another and this flow can indicate the beginning of a meaningful relationship. Likewise, when conversations are disrupted or otherwise difficult, this lack of flow can make people who have just met feel disconnected. But what about long-term relationships? Is a disruption in conversation as detrimental to couples as it can be for strangers?
