<human>: Can you provide a brief overview of the text?

Well, I was in high school at the time. The girl was one of those obnoxious sorts of people that become more and more difficult to like with every time she opened her mouth. And unfortunately, she never shut up. This girl was constantly rattling off how bitches need to stop giving her attitude, because she don't take shit from no one, and other, similar phrases. And she was LOUD.

So one day, the teacher forgets something from out of the textbook, and so this shy Asian boy, who probably spoke up twice altogether throughout the whole semester, raises his hand and tells the teacher what he had forgotten.

And of course, the girl has something to say.

"OH MY GOD, WHY DO YOU HAVE TO BE SUCH A SMART-ASS? THIS IS WHY YOU DON'T HAVE ANY FRIENDS!"
She'd given me a lot of attitude, because I sat right by her and she gives EVERYONE attitude, but that was far enough to where I felt obligated to do something.
Naturally, this girl also went to the bathroom to text all the time, claiming "girl emergencies" at least once a week, but of course, that excuse works every time, because a male teacher has to let her go, on the off chance that she's actually not lying. And then she'd come back and whisper Facebook drama to the girl beside her. Go figure.

I guess her period excuse was why it dawned on me that I was holding a red pen, and I got kind of inventive. While she was out in the bathroom, I took my red pen apart and tried to extract some ink. I couldn't make it happen, so I took a piece of lead from a mechanical pencil, dipped it in so that thick, goopy red ink stuck to it, and I broke off the wet part of the lead and tossed it onto her chair.
She came back and sat right on it, and it took all the willpower I had not to burst out laughing until the bell rang. It had smeared beautifully all over her white pants, right around the crotch, yet she walked out completely unaware. My life felt complete.
<bot>: A bitchy girl lied about being on her period for the tenth week in a row, so I put red ink on her seat while she was in the bathroom.
