Maturity is the ability to act your age. Many fangirls lack it. In fact, lack of maturity is often considered one defining characteristic of fangirls. For example.
'Maia' (though her mother calls her Mary) is a sixteen-year-old Legolas fangirl. At the age of sixteen, you are generally expected to be able to refrain from doing the following;
- Chasing strangers around making squeaking noises.
- Hugging said strangers if you catch up.
- Drooling.
- Wetting yourself.
Guess which ones 'Maia' would do if confronted with Orlando Bloom?
Lack of maturity correlates positively with increased occurrences of squeeing, glomping, stampeding, and writing badfic involving teh hott secks.
