Have you ever had to deal with a liar before? Someone who lies continually? About nothing?
I listened to one and the thing is, I knew he was lying. From previous experience, I know that there is absolutely no sense in trying to broach the issue with him. It just causes outraged tears and denials, and one little detail will be added to the story already told, and the detail is supposed to present the thing in a whole new light, and all the lies are supposed to become truth, and...but...it doesn't...it's just the same sad bullshit with another detail.
So I listened as he went on and on, telling his story, weaving in little details. I tried to listen and tell myself, "What does it matter?" because really, the story was inconsequential, as most of his stories are. But he talked on, and waited for our responses. "Awwwwwww!!!!" we were supposed to say. We were supposed to giggle at the right places. We were supposed to be charmed and think he was witty and cute. But he was telling a lie, and the longer he talked, the more difficult it was to listen.
What do you do? If you say anything, it will cause a huge emotional outburst, and like I said, one little detail will be added and he will look at you defying you to tell him that the story has not become completely true and believable. It's like dancing with smoke, the way the story shapechanges and grows, filling every corner of the room until you cannot breathe and your eyes begin to burn.
I hate it.
