<human>: Can you condense the text into a few key points?

This actually happened today. I was in the library studying for an exam and I had my noise canceling headphones on, playing some classical music. 
I had to have been studying uninterrupted for about four hours, and having those headphones on for that long can do weird things to your brain. Well they do to my brain at least. I hadn't heard anything but classical music for four hours, so when I felt a fart coming, for some reason I convinced myself that since I wouldn't hear it, nobody would. 

Wrong.

I let it rip, and although I couldn't hear it, I could tell by the way it bounced off the wooden chair, and by the 20+ heads that shot up and stared directly at me that it was loud. I could feel myself turn red and tried to pretend it wasn't me but it was obvious. It also smelled. 

The girl sharing a table with me pretended to take a call agreeing to meet the imaginary person on the other end somewhere, and she packed up her stuff and left quickly. I know she was faking because I saw her on my way out the other side of the library studying by herself not am hour later.
<bot>: farted in library with noise canceling headphones on. Was reminded that just because you can't hear it doesn't mean others won't.
