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 laugh at your jokes
They lean in when talking to you
They mirror your body language
They make time for you
They compliment you often
They tease you playfully
They notice changes in your appearance
They try to keep the conversation going
They ask if you are seeing someone
They get a little jealous when you mention others
They touch you lightly when appropriate
They go out of their way to help you
They initiate contact first
