Peter Pan Syndrome refers to younger generations' perceived unwillingness to grow up and their corresponding alleged immature behaviors (note: Peter Pan Syndrome is not an actual disease). This syndrome is said to be most prevalent in the generation born in the late 1980s and 1990s where the development of a sense of responsibility allegedly does not occur nearly as early as it used to. Possibly contributing factors might include over-protectiveness of modern parents, rising costs of living, and increased difficulty in finding satisfactory partners.
