The earth laughs in flowers*

People give flowers as present because flowers contain true meaning of love. Anyone who tries to posses a flower will have to watch its beauty fading. But if you simply look at a flower in the field, you'll keep it forever.
That is what the forest taught me. That you will never be mine, and that is why i will never lose you. - P. Coehlo, Brida
