U DONT
by the way she looks at you
With the sign of her eyes
It probobly means that her parents know about her crush and don't want to embarress her.
The girl and dad both want her crush to get to know her and they think that by the brother telling her crush that,that he will start talking to the shy girl beause that's her brother
introduce yourself and say hi, get to know her.
if he tries to show off in front of her
crush
I know he is dating "aimee coffey" shes on facebook. That was his crush before they started dating.
You ask the girl what her name is.
Mostly, yes. Some boys dont care or think about it and not know. Some boys take it seriously and know, if they also have a crush on them they will just go on as usual not changing mood.
Mabe the girl knows the brother and trusts him, or mabe she just needs somebody to talk to about her crush and wants to know what to do in this situation.
If you want the girl to know you like her, just tell her. You could do it with a cute little grin and say, "You know I have a crush on you!"
