Oh this reminds me if someone I used to work with. At first the rest of us thought she was just a bit of a drama queen. Then a chance conversation about something trivial opened our eyes to the fact she was going around lying. We all compared notes on other things she said and there were huge discrepancies. After that it became obvious when she was lying, we challenged what she said and asked her awkward questions and instead of backing off the lies just got more ludicrous.
Her landlord was throwing her out (although we could've believed that one and wouldn't have blamed him), her 3-4 year old daughter caught thrush from her housemate, she had the worlds worst periods - no-one suffered like she did, she had an ectopic pregnancy, yet carried on working for several weeks before it was removed, we know she did go to hospital but not for that - what she didn't know was that one of the girls mothers worked at the hospital and was able to check her out, - she was in a car accident with her boyfriend and her daughter fingers were broken, her mother came into work with the daughter the next day - her fingers were fine, and we weren't allowed to ask the boyfriend if he was ok when he came him because apparently he would get cross. Yeah right!.
The saddest thing was that one of the other girls who worked with us had a child the same age and in the same nursery/class at school and the daughter was starting to behave the same way
