If a girl like a boy then how a boy should talk with her at first time?

well it doesn't have to be all romantic.

all you have to do iis be calm and just say hi.

then ask her a question or somtheing like how was your day or what subject have you got next.

is she asnwers with i don't know or somthing short ended ask another question or complement her.

somthing like you must be smart if your in advanced maths or somthing like that.

xo good luck
