Is this person flirting with me because they have feelings for me or are they simply being friendly? Knowing the subtle differences can save you the embarrassment. So how do we know when people are hiding their feelings?  Disclaimer: This video is purely for educational purposes only and is not designed to suggest that if people do show these signs, that they have feelings for you. It is advised that you always talk to the person in question and discuss this to make sure that you are on the same page. If you feel like you cannot do this, then talk to somebody you trust to discuss your feelings.
