Flirting is making a friendly conversation. People associate flirting as a girl thing, but there are plenty of men who use it as a way to win a girl over. There is no such thing as being overly flirty, it comes naturally to people. There really is no way to teach someone how to flirt, but I can give you some tips on how to flirt and win them over. Flirting can be fun and easy!
Step 1: Look Approachable
You want to look nice. Not overly dressed, or looking like you just came from a dumpster. Relax, smile, and use your body language. Now, when I say use your body language, do not go huddle in a corner by yourself, so that cute girl/guy will come give you empathy. Instead, give them a nice flashy smile, or if you are braver, a tiny wink. Show them that you are comfortable and confident. Otherwise, you are not going to get anywhere!
Step 2: Read Body Language
Take a look at them. Are they approachable? Do they seem interested? If they are the one staring shyly at people, or are alone in a corner, then they are not the one to approach. Take it slow, and read them carefully. DO NOT STARE. That is a good way to prove that you probably are a stalker. Just smile with your eyes.
