Actually it varies from person to person. Yeah, indeed incessant talkers can make your time a complete disastrous one. You can become frustrated and get bored easily. I think the best way is to interrupt an incessant talker. How? Here are a few tips that can help you achieve your goal:
1. Try the interruption process periodically. Try to change the topic at times or tell your friend to stop so that you can talk. But try to do it in a polite manner so that your friend doesn’t get angry all of a sudden.
2. If you see that there is no sign of slowing down, just try to highlight that you are bored or irritated by bringing a gloomy or dull look into your face. This can make the talker slow down.
3. Never ever accuse your friend of being an incessant talker. This will only worsen the problem which you don’t want at all.
4. If you want to be a real good friend, tell the talker friend that you want to take a bit more part in the conversation. Otherwise you are not enjoying the talk at all. This might have a positive effect on your talker friend and you may get the chance to speak more during the conversation.
