ask a girl that you closely know and is serious
you ask the person if they did if they did they just wanted to be you
Get to know that person just like you would with anyone else and see where it goes.
Every girl is different. You have to know what makes her tick and what she likes. Sometimes, a person doesn't know that the other person likes him too. Knowing her birthdate is quite good.
if you mean, "is Adrian a girls name?" then no, it's unisex, meaning it can be for a girl or boy, if you mean "is this person i know called Adrian a girl" then only their mother can know for sure.
