your chance to offer some assistance; be aware that she will most likely be doing this on purpose just to see your reaction and hope that you will help out. When offering assistance, if there are other guys around and she actually likes one of those guys, she might be disappointed when you offer your coat to her first or offer your assistance. In this case, at least you'll know how she feels and can move on. You might even be magnanimous enough to tell the right guy that she fancies him. 8 Smile at her. Use your natural smile; you don't want to freak her out. If she smiles back politely, or frowns and looks away, she may be uncomfortable or disinterested. If she returns a soft or big smile and continues to look at you, then it's likely that she's interested. However she reacts, it cannot hurt to keep smiling her way. Eventually she'll get the message that you find her charming and she may feel able to open up more or at least to tell you openly that she's either interested or not. If she smiles then darts over to the crowd of her friends and hides in the group, then she may be nervous and curious about whether you know that she likes you. 9 Watch her body language . You can learn a lot about a girl by observing her body language and it goes well beyond obvious flirting signs into unconscious signals of attraction.
