As simple as it may seem to deposit a piece of rubbish into a waste disposal unit, some of us just don't do it.
And I am one of those some. Ever since the state took away bins from train station platforms (for anti-terrorism reasons), I've developed a bit of a littering habit. Slotting things into little gaps between train seats or just dropping something on the ground inconspciously as I'm walking is an easier alternative to waiting until I get off the train and finding a bin then. Of course there are places where I dare not litter, like at uni. Sydney University is so bloody clean that you'd feel immensely guilty should the barren ground become not so barren. But usually, if I'd have to go out of my way to get to a bin, I'd just drop whatever I have on the ground and be done with it.
Do you litter?
