They make eye contact with you often
They smile when they see you
They find reasons to talk to you
They remember small details about you
They ask personal questions
They respond quickly to your messages
They seem nervous or shy around you
They tease you playfully
They make time for you
They try to be near you
They initiate contact first
They compliment you often
They laugh at your jokes
They show interest in your life
They notice changes in your appearance
They mirror your body language
They touch you lightly and appropriately
They get jealous when you mention others
They ask if you are single
They keep the conversation going
They seem disappointed when you leave
They go out of their way to help you
They remember your preferences
They introduce you to their friends
They act differently around you than with others
