“It was the best of times, it was the worst of times, it was the age of wisdom, it was the age of foolishness, it was the epoch of belief, it was the epoch of incredulity, it was the season of Light, it was the season of Darkness, it was the spring of hope, it was the winter of despair, we had everything before us, we had nothing before us . . .” --- Charles Dickens, A Tale of Two Cities.

The above ticket belonged to coolboy. It carries some old memories of those best and worst of times. There is one piece of quotations from Chairman Mao on the ticket that says: “ The world is yours, as well as ours, but in the last analysis, it is yours.” Who actually owns the world? The natural world or the universe belongs to everyone, but if you understand it, then you own it.
