It's a few years since I graduated and I walked through my local university campus the other day, as I had reason to be in that part of town and you can do a short cut if you walk straight through the campus. I also stopped by at the students union to grab a cheap sandwich. It was very busy. Really, I'm not surprised it's having a bad effect on you. I had forgotten how competitive the atmosphere there was, I thought the vibe was pretty unfriendly with lots of the students coming over up themselves and pretty rude really (like on my way out of the union, this young bloke let the door swing back in my face, which I think he did on purpose). I would go crazy if someone put me in that environment again!
