Should I Be Worried?

So there's a new undergrad working in our lab at the moment. I don't know his name. Haven't been introduced - scientists are sometimes socially retarded like that - but he's working with the other group sharing our lab space. Ex-military - I do know that much. But here's the thing that has me slightly wary...

A few times today he's sat down at the computer next to my desk and gone about his business but in a highly suspect and unnerving manner. No idea what he's doing over there, but every now and then he seems to get extremely agitated. But in this weird silently explosive way.

So the first incident involved him reeling back from the screen, followed by aggressive rocking in his chair. Now I've been known to dance in my seat from time to time so far be it for me to pass judgment on someone else who is overcome by the sudden urge to groove. But his brand of rocking implied to me an intense flare of anger, requiring the convection of air around his head to cool the fires of a deep, burning desire to kill.

Then during the next episode, following about 30 minutes later, it happened again. But this time instead of the rocking there was a quick forward, downward thrust of the head, accompanied by clinched fists and arms shaking with rage. Perhaps he was trying to hide his face from me behind the CPU, separating his desk from mine? Maybe he was resisting the urge to punch something or someone? What is going on here???

The whole time this is happening, I'm concentrating on keeping my eyes steadily trained on my own computer screen and am in no way acknowledging that I am witnessing anything out of the ordinary or possibly life threatening. But part of me wants to scoot my chair just a few inches to the right and my posture is of the sort ready to spring into action at a moment's notice. Oh, yes, the fight or flight instinct is strong in this one, folks. I will go down swinging.

Yes. It is entirely possible that I am suffering from an extremely over-active imagination and/or experiencing early warning signs of paranoia often associated with schizophrenic dementia. However, just because you're paranoid, doesn't mean they're not out to get you. Therefore if I end up mysteriously murdered, I'd like one of you, dear readers, to please inform the police of these incidents and my concerns surrounding them. Thank you. Good night and good luck.

p.s. I love you, Greg, mom, Mel, Trav, Dad, Mr. Mac, Gomez, Noelani, friends and family.
