Every person is different. Some flirt only with people they like. Some flirt with everybody. Some are shy and don't talk a lot with people they like. Others talk their fool heads off. Some twirl their hair because they're bored. Others twirl their hair to flirt.
So the answer is there is no secret code. Every person is unique. You need to get to know this person, to know what THEY do when they're happy, when they're sad, when they're interested, when they're bored. The more time you spend with your person, the more you'll understand his or her INDIVIDUAL reactions.
Also, the more time you spend with your person, the more you can be sure this person obviously likes you, because the person is choosing to spend time with you and not elsewhere!
