First day of Spring Term – 10 weeks remain.

Nothing to say, my train of thought has sailed.

I didn’t think this actually happened. We lost our rugby matches the day this was taken, but also the next day so what does that say.

I can’t prove it scientifically, but I think the sun is actually brighter on days when I have off. The ironic thing is that I spend most of days off catching up on sleep, work and maybe going to the gym so the sun seems to only taunt me from beyond panes of glass. I’ll catch up with ya later, maybe at rugby practice.

Should I be freaked out by the fact that someone arrived at my site by searching for “scott perez fox”. I bet it was my father who couldn’t remember my site address and is too lazy to punctuate properly when using a computer.

Type in your own name in Google, the results may scare you.

*this message was accidentally deleted, by me, attempting to delete a spam comment containing lots of promotions for penis enlargements. Needless to say, I was pissed. I am attempting to rewrite this entry the way I remember it.*

The basement smells like the History Channel. Like when I was in high school and I used to knock out on the couch every night after wrestling practice and then wake up at some point in the night to hear the replay of the history channel shows and it would seem the randomness sunk in a bit.

The bathroom smells like the Maplewood pool, or rather me showering after a long day working in the stand, or roving, or swimming or just sitting in the sun.

*I don’t remember the third scent which reminded me of yesteryear. Sucks.*

So today is the last day of finals for this term. And, since I don’t have to take finals Spring of Senior year, it is the end of finals forever. So all I have to do is endure one more presentation and some bootleg grammar test and maybe another online test that I don’t know about and its over, bitch, no more finals.

In the words of Henry V, “Once more unto the breech, dear friends”

Last night Jay and I went to see the Complete Works of William Shakespeare, Abridged at the Philadelphia Shakespeare Festival, which, by the way, is a glorious misnomer and I would sooner call it the Philadelphia Shakespeare Company, as opposed to festival. Anyway, the show. It was mad funny, thats about the long and short of it. The way I could tell was how Jay was laughing….at Shakespeare. This is a guy who swears by Chris Farley movies and Jack Black music. (Jack Black makes music?). Still, there was just enough old-fashioned Shakespeare to keep me level amidst pop culture references galore and low blows at the Republican Party and intellectuals in general. I could have done without the vomiting as a recurring gag. Oh well.

Wouldn’t it be grand if I have enough time to just watch plays and write in my weblog. One day…hopefully soon.

Enough of me saying nothing, I need to go and give a presentation and make up shit on the spot to impress and otherwise-stoic class of soon-to-be lifeless engineering types. I swear, I make it all up as a go along and they are amazed.

Here are some old shots from the last dance show. I blame Photoshop CS, and their actions not working for the delay in this case. Don’t ask me what the hell is going on.

I tried to fix the archive section of this site but instead I broke it and now it doesn’t work. Sorry.

In other news, I survived this week. Time to take finals for the last time in my life.

Yea. I don’t understand it either. Don’t understand it either. And by the way, its completely wrong and I just made up answers for which to submit. Do I feel guilty? What do you think.

Sorry, the video of Pete doing body shots off that bust Slovakian girl didn’t come out too well.

“Laura and Allison” thats all I know about those girls. End of commentary.

So its week 9 of winter term which means, among other things, that I get really busy all of a sudden trying to make up for a whole term of slacking of and vaguely paying attention to life in general. It also means Spring break is just around the corner. Of course I don’t have any money for exotic trips or lavish adventures, but rather just to catch up on work around the house and maybe get some stress-free sleep.

So, don’t kill me if I don’t blog for a while, I will be pretty busy with my descent into madness.
