Hubby and I are having a situation with a family member who keeps lying to us.
Her lies aren't even important ones and don't affect us, but they are lies and we know she's lying. Then, like tonight, something will come up where we hear an entirely new version of a story. She told us about an incident that occurred several months ago and realize that tonight's version is in fact the true version (mostly) and that the original version was a falsehood. She doesn't even remember telling us a totally different version earlier.
This is happening with more and more frequency. She's lying to make herself look better and also to cover up her own selfishness/vanity. It's sad, really, because I don't think it's with any attempt to harm anyone but merely to make herself look better.
You know what? If you tell the truth, you don't have to worry about keeping your stories straight.
