Smiling and crying is the truest interpretation of crying; falling in love and being separated is the saddest ending of separation. It is difficult to see without a microscope, but it is successful without a telescope. Only the true need heart knows, people who really care often don't know, so there will be love and hatred. People grow up, their hearts change, and time carves their hearts. If you don't pay attention, things will change, so that you don't even recognize yourself when you think about it.
