Nature teaches us a lot about freedom. None of the plants , clouds, mountains ,valleys ,plains show resemblance, they are all unique.The pattern of leaves, the petals of flowers.Nature gave us the freedom of choice, choice as in 'i like red', 'he likes blue','i like cabbages' and 'u like bitter gourd'. These choices add a uniqueness and actually shape up one's personality.This world would have been seriously depressing,were it all black and white. So its against the Nature to supress one's freedom, one's freedom of choice,of thought,of expression. So feel free and put your colours on.
