There was a girl my freshmen year that "flirted" with me thoughout the year. She was cute and all, but I was never sure if she was being serious or was pulling a prank. I am a quiet person around people I don't hang out with, so she did not really know anything about me except I was a nerd in terms of class performance. Evenetually, a guy in the class asked me if I liked her or not. Of course, I wasn;t going to say outright that I though she looked nice, so I played it safe saying shes not my type, and she overheard it. To this day, I don't know if she was pulling a prank or being serious, but she did stop "bugging" me afterward which makes me regret being as cautious as I was.
