That is very interesting, I moved to a new city about 2 years ago and began working in an office setting. For the first few months i did not have regular contact with front office staff, as I was in the back office, but moved to the front and got to know the rest of the staff, one of them being an egregious liar. Her worst offense was criticizing everyone's meal choices at lunch and bragging about how she eats healthy, exercises, finds red meat and white potatoes disgusting, etc...but then sneakily raiding every candy jar in the office. (!) All of our positions were entry level paying about $15/hr and she frequently bragged to several co-workers and myself (but did not tell certain people including our boss these things) that she had graduated from a prestigious medical school. Nothing but lies upon lies upon lies from this woman. I avoided her as much as possible until she finally quit. Apart from the lies she was also incredibly rude and condescending.
O.P...when you say is the lying strange, yes, it is! I lived in another city for 23 years before moving to my current location and never encountered anything like this.
