What is love?
In fact,love is the eternal topic for all human beings,and not easy to give a one sentence definition.
Love is the rain in spring that can moisten everything.Love is the breeze in summer that can make us feel cool.Love is the fruits in fall that can let us feel the joy of the harvest.And love is the sun in winter that can keep us warm.Love is as beautiful as flowers,love is as wide as the sky.
