Here's a tip from years of nerdy library attendance: if you want to have a really productive day in the library, go in on a Friday. For some reason, which I'm sure someone somewhere has figured out, libraries are almost completely deserted on Fridays. You could fire a cannon through the main room and you wouldn't so much as graze anyone on the elbow.

Other days, it's stacks on, everyone fighting for a seat, hundreds of people rushing about with their mobile phones, talking to their friends, dropping things, crossly standing in the "15 minute" internet queue (it's never fifteen minutes) and the old favourite: a hilarious ringtone chimes ostentatiously, followed by a fountain of guffaws.

I suppose it's the students. When I was a student, Friday was like the weekend. You spent most of it intending to get your essay done and ended up going to the movies or bumping into someone from your politics tute sitting in the sun with a beer. Several times I went to the wrong party in a street in Carlton and ended up having a lovely time with an entirely different group of people, some of whom I even recognised from uni. I always yearned, back in those days, for weekends without the essay guilt. I yearned for a five day a week, nine to five, ordinary, normal job. Possibly because I knew I would never have one.

Of course, now, I have The Guilt just as much as I used to, only without the satisfaction of being graded for the work I hand in, and without the student elections and the cheap Indian food after six in the evening.

So here I am on a Friday again, in a library, with a deadline hanging over my head and a cafe/bar outside where I bump into people I did politics tutes with. Honestly. Yesterday, I bumped into the friend from school with whom I first started a theatre company at Melbourne University. I remember the two of us filling out the forms, writing the dates of the play in our diary and thinking, "Well, we did it - what next?"

She's a writer now. She's been doing her PhD. The deadline's hanging over her and she really should be getting it finished, she said, as a friend sidled up to her and ordered them both a coffee.

I'd already had mine, so I had to go back inside and fight for a seat in the library.

I have always thought there is a word missing in the English language. I don't know if there's a word for it in other languages or not, but I feel there should be a word that describes the sudden sensation or recognition that a lot of time has passed and many things have happened but CONVERSELY AND SIMULTANEOUSLY that not a lot has changed and time feels compacted - as if we were just here and we left for a moment because one of us needed a drink and then when we came back, eight years had passed.

Perhaps I haven't expressed that properly, but the feeling of time having passed both slowly and quickly is a sensation I have quite often as I get older, particularly as I go through all my old routines, such as sitting in a library after a coffee with a friend and trying to refocus on what "really" matters.
