When you're happy, you enjoy the music. But when you're sad, you understand the lyrics.
Being upset can be a natural reaction when things go wrong or something bad happens. You may get upset when you are ignored or if you get into an accident because another driver was not paying attention. Being upset can also happen if a romantic relationship ends or if someone you care about passes away. When you are upset it is important to calm down and try to think about things more clearly before you take any action.
