We've all had that experience. The acquaintance who moans non stop about her love life (or lack of); the awful uncle at the family party; the work colleague who can recite entire episodes of Buffy The Vampire Slayer.

An article on lifehack.org has one suggestion on how to escape:

> Try and confuse the person into wanting to exit the conversation. You can achieve this by bringing the topic of conversation to something off topic, only constantly. Interrupt with strange anecdotes and respond incorrectly and indirectly to questions. Have your own conversation without considering what the other person is saying. Start your own rant.

Alternatively, if you're taking things a little more seriously, you might want to try to steer the conversation to a topic of mutual interest. That or pretend you have to go to the loo.
