Mirroring the stance of the other person is a classic body language tip to say “I’m interested in you”. Feet pointing towards each other, legs crossed towards each other, but crossed legs could also mean not interested too or it could just be a comfortable way to sit. Too strong looking might be threatening, but just enough chest out for guys might be appealing – such a fine line!
Direct eye contact is probably the most reliable way to tell if someone is interested and anything like an eye brow raise or a smile is a definite invitation that the person is interested and wants to talk. For confident flirting put your thoughts of ‘fear of rejection’ or your ‘tough city look’ or ‘I’ve had a bad day and I don’t want to engage ‘ aside and have a chat and you will be surprised what you can learn and where it might go.
