Answer:
In the ancient and modern worlds, the poet (who is also the speaker) communicates to his kid about human behavior in the past and today. In "feel at home" his meaning to this: once, twice, there will be no thrice for then I find doors shut on me. He recalls a period when people shared true affection. They would laugh heartily and convey genuine emotions to one another. However, in today's fast-paced society, people regularly exchange frigid handshakes. They exchange greetings with a smile or laughter that reaches their eyes but does not reach their hearts. They are simply being courteous when they say 'come again' to a guest. According to the poet, people nowadays are frequently more interested in meeting those who are affluent, powerful, successful, or renowned than in meeting those who lack income or position.
