That was late May in Sydney. I travelled home from uni with Maggie. BTW, I didn't get along with her. She is not that kink of girl you like. And I don't imply she is mean or sth. It is just she is not so agreeable.
It's a double-decker train, and the journey will take 20 minutes. Speaking of the trains, it is claimed that Sydney has the world's most effective train system. Lots of efforts, money and manpower are put to keep the train running as smooth and punctual as possible.
I once did a data analysis about Sydney's train system, in which I was given a set of data (around 735) to analyze the candidates' travel behaviour, how they view the public transport, and above all, how the two are correlated, and in which way to improve the performance of public transport, by using some sophisticated techniques. In my report, certain complex-looking models were run, with which two seemingly clever functions were laced. I even came up with some very inspiring suggestions to the pretend manager of transportation head office. That was fun.
Finally, it was concluded, the bus is the most preferred travel mode, except for car, though I like the train better. The trains are filthy, no doubt about it, but they are very user-friendly, and stick to the timetable most of the time. You don't need to worry about things like, taking the wrong train, getting off the train at the wrong stop, or that sort of thing. Maybe, for the first few times, when you are not accustomed with Sydney's train system, the timetables and different train lines would look messy and too complicated. But you will get better, once you know all the "tricks". By then, taking trains in Sydney will be the easiest thing you've ever done. At least, that's what I think.
Alright, back to the point, I was sitting on the upper floor of the double-decker train, talking to Maggie who was sitting next to me. I couldn't remember what exactly what we did that day. All I can recall is that it was commute time. The carriage was filled with exhausted/indifferent-looking people. Some of them were sitting, with free newpapers in their hands. Maggie got one too. That's the first time I've ever heard of or seen a Sudoku. I knew Crosswords before, though I never solve one, or even try to. That would be a huge challenge to my vocabulary. I don't think I can do it. All the English words I can "summon" are around ten thousands, and that's just primary school level for a native speaker, far from enough to solve a crossword. If it wasn't Maggie, I would never set my eyes on that little crosswords-like game. She picked a pen and concentrated immediately on the game. I was watching, uninterested.
A moment later, I got clues about how it works. I joined her, which, later on, was approved to be a stupid move. Two people can not solve one puzzle. We got mixed up, and failed to finish the game. She was annoyed. And I found myself a new hobby since then. It's time-consuming, and making you feel like a loser sometimes. But it's fun for the most of the time.
I started with the level marked as "Easy", then reached gradually to the higher level, not the utmost one. My basic techniques are raw,
