Not Quite Social

Robert Frost is my favourite poet (that might be because he's the only one I've actually read) but I often get the feeling that I'm missing the whole point, or the picture... Either way, I was wondering if you could tell me what you think Forst meant with a the following lines in Not Quite Social (A Further Range):

To punish me overcruelly wouldn't be right
For merely giving you once more gently proof
That the city's hold on a man is no more tight
Than when its walls rose higher than any roof

I don't know. I think poetry is difficult. I never know whether there's an actual meaning behind (a part of) it or whether the poet simply chose a word that rhymes or words that "feel right." It makes it dificult to enjoy.

Anyway, thanks.
