The sadness.
We all feel sad sometimes. Sadness is a normal emotion that can make life more interesting. Much art and poetry is inspired by sadness and melancholy. Sadness almost always accompanies loss. When we say goodbye to a loved one we usually feel sad. The sadness is even deeper if a close relationship has ended or a loved one has died.
Sadness also helps us appreciate happiness. When our mood eventually changes from sadness toward happiness, the sense of contrast adds to the enjoyment of the mood.
