Precocious: 1: exceptionally early in development or occurrence
2: exhibiting mature qualities at an unusually early age
I had a discussion with a friend of mine about a patient who I described as precocious. It was a disheveled conversation until I realized that his interpretation of precocious was negative. He thought that word implied that the patient was intellectually capable but socially immature. We looked it up and it appears I am correct. I have always used 'precocious' as a compliment and assume others do as well...
