Does your date have Imposter Syndrome?

Have you ever met someone who presented themselves one way but later proved to be someone completely different?  Imposter syndrome is common and that is what my friend Max just experienced.  His first couple of dates with Lisa was pleasant and fun.  He even thought she had a sense of humor.  Fast forward a few months and lighthearted Lisa rarely even cracks a joke and seems to have an anger management problem.

How do you handle it when the people you date “transform” into someone with a different personality?  What is the difference between imposter syndrome and putting your best foot forward?

Do you think you can tell when someone is being authentic?   Can you spot a poser?
