IF the liar is a child under your control, just sit them down and say you aren’t planning to move until you hear the truth, and you’ll know the truth when you hear it. Then get the kid a bowl of pastini, take out your knitting and make like you can sit for one hundred years. And mean it. Sooner or later they’ll crack.
IF the liar is an adult, or a child over whom you have no rights and you aren’t the State District Attorney, you have a bigger problem. If someone is lying behind your back, you can always make them say it to your face in front of witnesses. They’ll deny for sure, then you have the necessary means to label them a coward. If they are lying to your face, you need to decide if it’s the ditch you want to die in. If it isn’t.. well, they can either be dead to you or you never trust a single thing they say without checking. If it is, then you call them on it.. whatever it takes. Hire a detective, lay a trap, follow them yourself. The problem with all this is that you give them power over your peace of mind. Depends on how big the lie is and sometimes, knowing the truth has its downside.
My cousin Louella had an inkling that all was not on the up and up with her hubby and a certain co-worker. A large inkling related to the fact the co-worker’s husband called her to commiserate, and see if Louella was interested in revenge that came under the category of good for the goose, good for the gander, if you know what I mean. Louella confront her hubby, who denied. Now, Louella didn’t really want to know. She decided to believe her hubby, who decided to break it off with his lady friend. Which I believe had something to do with the difference is body fat to muscle ratio between him and the other guy. (The reason I know all this is that the co-worker lady in question spent three hours sobbing at my Formica table, asking what should she do.. but that’s another column) And Louella is very blissful, thinking that all is well. I’d tell her she was crazy, but she hasn’t asked.
