It really depends on who the person flirting with me is. There's this lady I work with named Mary. Mary weighs about 350 lbs of sagging flesh. Mary has bad acne, braces, thick glasses, and she's the type of person that you can tell, even if she cleaned up, she'd still be ugly. When she tries flirting with me, I get angry.
But if someone more attractive flirts with me, I'll generally flirt back.
Also, with the chicks playing video games, I actually used to date a chick gamer. She was the ****.
