Step 3 - Read body language.

Read body language. Does the person look approachable? Do they appear interested in you? From the moment you see someone with whom you might want to flirt, you should read his or her body language. Once you're actually flirting with the person, body language is often the only way to tell if the person is actually interested in you . We all have a natural ability to read body language, but it's easy to misread signals, so be careful and take it slow. If you see one signal that indicates the person is interested in you, watch for other signals that might confirm that.
