Being flirty is a “cheap” way of attracting attention to oneself and the “wares” a girl has to 
offer. It’s using subtle body movements and charm and flattering words to get a fellow to notice her — to like her — to date her. It’s an expression of self centeredness and immaturity. Most men don’t “like” a flirty girl in the truest sense of the word. They may find it momentarily cute — but degrading in time.
A mature, feminine friendliness, on the other hand, is a gracious art that men find very appealing. We’re talking about expressing a genuine outgoing concern for all people in general. She’s able to make them feel respected and important, relaxed and comfortable. Kindness and compassion are trademarks of her life. Her profile is milder and sweeter — more becoming than the woman who tries to flirt her way to popularity and success.
