I think it’s about a family that owns a farm and they grow only oranges in the farm. They sell the oranges to get money.
The poem is about a boy holding hands with a girl for the first time and he wanted to buy her something. He took the girl to the store and she wanted chocolate but he only had 5 cents and the chocolate cost 10 cents. So he put 5 cents and a orange in the counter.
It’s about how much this boy likes this girl, he likes her so much that he ended buying her a chocolate that he didn’t have enough money to buy it, But he ended up buying it anyway with an orange. The theme is about how much this boy likes his girlfriend that he would buy something for her even if he can’t afford it.
