Human's tendency is to be lazy, so lazy that once they could rest, they would.. When thomas edison invent the lightbulb, they had been living in centuries without it, but yet as it brought them so much convenience, they would now not be able to live without it.. It is just like walking towards darkness, it is near impossible to see a thing, especially when you were in a bright and comfortable room. yet, if you've always be in the dark, you will just get used to everything around there. they need to grow up, it may be tough, but is definately compulsory.. to get use of the dark tunnel, the invisible tears that accompanied them, the silent from within..They have to be brace- so brave that nothing can affect them anymore.. Its not what normal people can do, unluckily, i am also not one of them..
