Are You A Know It All

Have you ever met a know-it-all? The are a jack of trades and the master none. Don't you have fun when some of your friends get together and their is one person who knows everything and corrects everyone who talks. You say last June we went to the lake they jump in and say it was July. Who cares what month it is does not affect the story at all, but the know-it-all has to chime in. Know one likes a know-it-all.
