They make eye contact with you often
They smile a lot when they see you
They find reasons to talk to you
They respond quickly and seem engaged
They remember small details about you
They ask personal questions
They laugh at your jokes
They try to spend time with you
They initiate contact first
They seem nervous or shy around you
They mirror your body language
They compliment you
They pay extra attention to you in groups
They notice when you are absent
They make an effort to help you
They touch you lightly in casual ways
They seem interested in your life
They keep the conversation going
They make future plans with you
They act differently with you than with others
