There is one person I know in particular who keeps doing this, and they just won't stop. It's a situation where I'm this person's only real friend and the only one who can help them with nearly everything in their life - but they keep lying to.............. save face? There is nothing particularly interesting that ever happens in this person's life and they don't really have any face to save, and these lies purely undermine me by misleading me or costing me time or money. Again, there doesn't appear to be a rhyme or reason (that I can tell) for them to tell these lies. Why are they doing this? Is there something I can say or do to make them stop?
