A lovely smile is actually a good sign and, when it comes to flirting, it’s one of the surest signs he is interested in you. If you notice that he is smiling at you, there’s a good chance he likes you and wants to approach you. Maybe he is shy, so why not show him your confidence and courage by approaching him first? Of course, if you like him. After all, there is nothing to be ashamed of if you approach a man first. Just smile back, initiate a conversation with him and don’t try to play hard to get. Playing hard to get is a great boost, but often it’s a big turn off for guys.
