Once you add black to white,

it will never be white again.

Once you add black to white,

it will always be gray.

Once you add black to white,

it will always be gray.

No matter how much white you add,

it will always be gray.

The more black you add, the darker the gray.

Every time you add black to white,

you get a different shade of gray.

Until one day,

when it's black instead of gray.
