The most important thing? Be nice. Smile, and carry on the conversation you are having.
If you like her, you should flirt back. Be sure to look her in the eye, and smile. During a conversation be sure to direct some questions at her, so that she knows that you're interested in knowing more about her. Depending on how well you know her, it may be appropriate to go beyond just eye contact; touch her arm, playfully (and gently) push her, or if you're incredibly daring brush a piece of hair out of her eyes. If you are walking be sure to open doors for her as you go. Next time you see her be sure to say hi, even if it's just a quick wave in the hallway.
If you don't like her, you still need to smile and be nice. If she likes you, you don't want to be mean. If she's flirting just because it's fun to flirt, you don't need to be a kill joy. If she is pulling moves on you, evade them. Side step if she goes to put her arm around you, change the subject the moment the word "sexy" comes up, and politely excuse yourself if she mentions her childhood pets.
flirt with him back if you like him, if you dont than walk away
You should try to flirt back if u like him... If not then confront him and tell him what he is doing...
A girl who flirts a lot probably just wants attention.
