Reference: This line is from the poem, “Once upon a time” written by Gabriel Okara.
Context: The poet says these words while describing people’s attitude if someone visits their house.
Explanation: The semblance of cordiality will disappear if one visits for the third time. When they say “feel at home” , it applies only once or twice. In fact, they would shut the door on his face. One should not believe those words and visit their houses frequently. Familiarity breeds contempt.
