There are people who lie. They lie so easily that it is shocking. Even though you know for a fact they are lying, they will insist. They will get louder and more belligerent.
These people can’t do better.
They live in their fantasy world and can not leave. They invent their world, and try to force reality to conform.
There are those who need attention.
Sometimes they’ll act as if they want to be alone so that if you speak at them they can bite your head off.
Other times they stand near to you and babble on the phone as if they can charge you for eavesdropping.
Sometimes they will jump in your face with some attack, either on you or another.
And if you slap them with silence or disinterest, you bust their balloon.
