So you're fluttering those lashes and baring those pearly whites but getting nothing in return? It could be something to do with your body language.
Jean says: "Using your body language to flirt is something you need to get your head around. It's all about sending out signals of approachability, you have to look open to someone coming up to talk to you in the first place.
So rather than facing in or towards your friend at the bar you would face your shoulders and body out towards him. This lets him know that he's the one that you want."
Think you can manage that?
