Emotion will affect a person's life. When you are happy, everything you see is beautiful. For example, if your classmate accidentally broke your pen today, you will feel indifferent and leave him alone. Similarly, if you fail in the exam, you will be annoyed at the thought of being scolded when you go home. At this time, your classmate accidentally broke your pen, and you will vent. If you pursue the person you like, you will be full of joy. When you come home and get scolded for failing the exam, you will think your parents are cute. On the contrary, if you confess to the person you like and are rejected, you will be very sad at this time.

It's not easy to hit by hand, hope to adopt it.
