Explanation:
The poem I, Too
BY LANGSTON HUGHES
I, too, sing America.
I am the darker brother.
They send me to eat in the kitchen
When company comes,
But I laugh,
And eat well,
And grow strong.
Tomorrow,
I’ll be at the table
When company comes.
Nobody’ll dare
Say to me,
“Eat in the kitchen,”
Then.
Besides,
They’ll see how beautiful I am
And be ashamed—
I, too, am America.
What the speaker meant by tomorrow is "in the future when there is equality".
The poem is about racism in America again the black and how the black responded to it.
The blacks in America are hoping for equality in the future when they will be treated the same way whites are being treated and they will enjoy the same privilege as the whites.
