Blue Wall / Green Wall

What comes to my mind when I see a green wall? A green wall reminds me of the grass so green And the emerald most rarely seen A green wall reminds me of the leaves so green And a forest where I have never been A green wall reminds me of trees with a lot of shade And the fresh vegetables kept for trade. What comes to my mind when I see a blue wall? It reminds me of the sea so blue I feel like jumping in it too A blue wall reminds me of the blue sky You can’t touch it cause it’s very high A blue wall reminds me of the deep blue bear It is very dangerous so beware A blue wall reminds me of a blue whale To reach it from the shore you have to sail.
