Dear Queenie,
My mother is a terrible liar. You just can’t believe anything she says about what she has been doing, or about anyone else for that matter. I make it a habit to check up on whatever she says so I will know the truth, but it is a pain in the neck (and in another part, if you know what I mean) to have to do so.
Many times I have told her I checked out what she said and confronted her with the truth, but she continues the same old tricks.
Queenie, why does she do this?—Disgusted daughter
Dear Disgusted,
Probably she lies to gain attention and/or sympathy, and to manipulate others. By checking out whatever she says you are handling the situation as best you can.
All else you can do is limit your contact with her, and if she complains about it tell her exactly why you are doing so – not that it is likely to get her to change her ways, but at least you will not have to put up with her lying.
