I am expressed by four letters,
yet the significance of my oration brings considerable alterations to society.
I love and I hate
I plant and I pluck
I build and I destroy
I give life and I kill
I construct and I demolish
I sing and I conceal
I laugh and I cry
I am peace and I am war
I am calm and I am loud
I am good and I am bad
I am light and I am darkness
I am just a WORD.
