I get lots of mail from girls between the age of 18 - 22 looking for their prince charming. That is kinda cute in some way, but honestly: age isn´t just a number. A lot happens to a person between the age of 20 - 30, and thats a journey you should experience with someone around your own age. I know you feel mature, I did too already when I was 17. It´s ok to feel like an adult, but please respect this: I´m not interested.
