Very Early Ramblings

I'm on the tube, and it's 5.30am.
It is a sobering experience being up this early, but what is extraordinary is how many others there are who seem to start there day when sensible people have only just gone to bed. I had to wait for a seat on the tube. I had to WAIT FOR A SEAT at 5.30 in the morning. When I told my mum I was leaving at 5 she was concerned for my safety, as this is a time traditionally observed only by milkmen and rapists, or so we thought.
The tube is clearly divided between those who are up, showered, fresh and ready to crack on with their day, and those who most certainly aren't. A few look quite shell-shocked, as though they have no idea at all how they got here.
One gentleman has a beer open though, which I find particularly impressive.
But I can't understand why there are so many people with the need to be travelling at this time. I can think of literally 3 jobs which require you to be in before six. Like, for instance, fisherman. But I don't reckon a fisherman would get the tube to work.
Suggestions to this point on a postcard please.
I'm going to sleep now.
