I spend alot of time in alot of different places in town. I see alot of the same women day after day.  
My question is this.  
When a pretty women smiles at you in what appears to be a genuinly sexy type smile, every time you see her. Does that mean anythng or are some women just friendlier than others.  
Is there a specific type of smile that a guy should watch for? what about other signs? Playing with hair? Intentionally touching a guy. Not smilling at a guy??  
 
Now I dont expect you girls to give away all your secrets. but for some of us guys we need a little help once in a while.  
 
Looking forward to hearing the responses from this one.
