Tears can be cause by so many things. They can also mean many things, but they can mean more to someone, who may live no more. They can mean pain is present, they can wash away pain. They can mean sadness, they can mean happiness. They can be caused by distress. They can be caused by Anguish.
Tears can mean that a person is caring or understanding. They can mean that a person is tender hearted, or that someone loved had departed, but for a dying being, tears are shed for a lot more. They are shed for the things they will never have. They are shed out of dread for dying young. They flow freely from the heart out of sadness for being rejected so freely and easily.
Tears can be for any feeling, but can never be matched to those of a dying being.
