look towards him flash him a sexy slow smile, then glance away, and then after a few seconds return your gaze back at him, repeat until he smiles back if he smiles back you could always go bold and wave him over or you could do it again then sorta flip your hair behind your ear with your hand, smile, look away and do the same thing, eventually if hes intrested he will come up, it shouldnt take him long as long as your keeping on a sexy smile and flirty eyes





hope i helped =)
