SADNESS

Death,

Bad weather,

Lost fo someone,

Bad grade in school,

Sickness,

Diseases,

Accident,

Traveling in the subway,

Bad food in restaurant,

Bad movie in cinema or TV,

When some steal from you

Lie,

When you can't sleep at night,

Bad school day,

Break up with girlfriend,

When you love someone, but she's not,

Fight with someone,

When someone tell's you "I don't love you any more and I never will !!",

When someone is screaming at you.
