Answer and Explanation:
"The Walrus and the Carpenter" is a poem by Lewis Carroll. The Walrus and the Carpenter are walking on a beach, inviting oysters to come and walk with them. Several young oysters end up following the two.
Why did the eldest oyster choose not to come along with the Walrus and the carpenter? How did he convey his intentions?
The eldest oyster is wiser, more experienced than the young oysters. He could perceive the Walrus and the Carpenter's true intentions. To convey that he did not wish to come with them, the oyster simply "winked his heavy eye, / And shook his heavy head." He was right to do so. In the end, the young oysters are eaten by the Walrus and the Carpenter.
