working the eye contact

if you are near your crush at any time just look out of the corner of your eye to see if he looks at you and when he does look at him and GENTLY bite your bottom lip innocently. DONT try to look as though you're trying to be sexy otherwise he might think you are being too forward and then look down and smile to yourself. guys SHOULD find this cute and then they will know that you will like them.
if he looks at you DONT smile straight away, wait for about 2 seconds and then smile WITH YOUR MOUTH CLOSED. NEVER smile with your teeth showing because this signals a friendly sign and you want it to be more than that.
