The father inquires, “Do you care about the earth the way you care about other things?” At which point they begin to discuss the things they care about, the family, Blackberry the family dog, and they discovered the list was relatively short.
The following morning as they leave for their respective daytime destinations, the father asks again, “Do you care about the earth?”
They answer in unison, “No.” As they enter their car and take their respective seats the son pauses and suggests the following from the rear, “It’s really about being grateful. If you’re grateful, then you will do something. The earth can’t care about you so how can you care about the earth. It’s not the same.”
“That's brilliant”, the father says as he reflects on how grateful he is to have children. He also realizes that he didn’t take time to acknowledge his daughter for being who she is and the father makes a point of rectifying this later the same day.
(The father makes a mental note about how the earth may in fact 'care about us'.)
