Hello Kitty Syndrome 

The female version of the "Peter Pan Syndrome"; a grown female who behaves and/or conducts herself immaturely; childish; female that is not accepting to "grow up" and behave her own age; female regression to her childhood.

Some people would say she is having a midlife crisis at age 35 because she loves going to bars every weekend with her 21 year old friends instead of settling down. I suppose she suffers from Hello Kitty Syndrome.
