Your friends tell you i dont flirt enough and you think you do but you are really shy but what do you do in order to flirt and how do you know if the person flirts back?

first, tell your friends that you do flirt and if they don't believes you you just ignore them. second ,stare at him/her with a common look and wave at them but don't let your teeth show because then you will look cheesy. and third, if he waves at you back with a cool look then he likes you, or if you see him in the hall ways staring at you that means he likes you too and if he/she does not he probably is shy. another way is that start pretending to date a person and if she/he does look mad at the person that you are dating then that is love if none work she/he is just not into you, so find someone else.
