Rated X-Experiences in the computer room.

So I'm in the computer room in college and this girl comes in. The guy next to me stands stands up and opens up his arms, and starts making out with this girl(Seriously, being extremely affectionate). Starts "smoothing" down her back with his hands, she has her arms around him, pauses for half a second, then looks into his eyes(Yah, I'm typing this out as I see it, lol.) Suddenly, as if hit on the back of the head, she lunges at his face and starts______(I left that blank because it seems as if she's trying to choke him to death with her tongue, or trying to fit her head in his mouth.It's either one or the other or both, go figure).

Yah, college is fun and all I suppose, and I do witness this a lot. But seriously, why in a "quiet" computer room, why not just go back up to your dorm? Most importantly, can't you tell I'm sitting right next to you people?(I have a hoodie on, so perhaps they assume I just don't care if you they have specks of spit flying around, etc.) One more thing, I left out the fact that they don't mind being noisy about it either.
