Even if you are busy, even if you are anxious, you should say I miss you in your spare time.
Even if you are tired, even if you are depressed, you should say good night when you want to sleep;
Even if you are angry, even if you quarrel, you should squint and smile when the sun is dim the next morning;
Even if it is boring, even if it is dull, we should hold each other's hands tightly in the evening street.
We all agree that a lifetime is enough.
