Have you ever been at an event and found yourself in a conversation with someone you have absolutely nothing in common with? You have most likely felt trapped. Here is a way to exit that conversation without offending that person:
As you close the conversation, shake the hand of that person and comment on something they discussed with you during the conversation.
For example: “It was a pleasure meeting you Joe. Good luck in your upcoming chess tournament.”
Don’t make up a lie for an exit strategy. That person will see you did not visit the restroom, get a drink, or make a phone call.
