Ballad of the Caged

I was in a zoo when I got these words, There was happiness and smile on every face, There were animals, plants, ponds, and birds, The cheerful delight was coming as they were base, But they were telling me they are caged, They give delight but they only have despair, And we as animals are in only clicking photos engaged, They were telling we don't have food, water nor fresh air, We are totally disturbed by your interfere, You have smile but we can't even cry, Nor we can show our pain, to us joy never appear, A ticket for our show invests in our cruelty, so please don't buy, It's so sad we can't hear nor bear their ballad, I wonder how can we trap them, we are not God.
