You are waiting for a flower, just like waiting for an old friend. What do you mean?
You live to wait for a flower to bloom and a person to return. Explain that this person's life has a certain goal. If we have no goal in life, then our life is boring for two people, and we don't know what we live for. Only when we have a goal in life, and strive for our goal, will our life be rich and colorful.
