"I, Too" is a powerful poem by the popular poet Langston Hughes. It is about a colored individual who is forced to eat in the kitchen whenever company comes. He talks about "they" and refers to the people who make him leave when there is company. He says they will be ashamed because while they send him to the kitchen all this while, he is getting stronger and better.
