That’s because this is a literal poem about a literal situation. Frost was writing about a real situation, not some esoteric wall or fence that didn’t really exist, or some deeper meaning with a lot of imagery that x stands for y, etc.
People like to read into poems things that aren’t really there. Sometimes a poem is just a poem.
Sort of like the Bob Dylan fans that ‘see’ in his lyrics a whole set of deep thoughts and inferences that exist only in their minds. He laughed at them. His Rolling Stone interview a couple of years back was a real eye opener. He would put lots of imagery and flowery words in his songs, mostly because the words sounded good. People, hippys mostly, made pilgrimages to his home in upstate NY and he was angry with them for invading his property. He said, “I wanted to set these people on fire!” and he was being very literal.
I don’t think Frost was trying to convey anything except a little story about his neighbor’s wall and what his thoughts were on the subject.
Sometime people try to be more intellectual than intelligent.............
You are completely wrong. There is no such thing as a literal poem. Poetry is the opposite of literalism. Your example of Bob Dylan is irrelevant. This is like discussing music with the tone deaf. Please stop.
