We have two daughters: Kristen is seven years old and Kelly is four. Last Sunday evening, we invited some people home for dinner. I dressed them nicely for the party, and told them that their job was to join Mommy in answering the door when the bell rang.

I was about to serve dinner when I realized that she had been missing for twenty minutes. I ran upstairs and found her in the bedroom, crying. I said, "What are you doing, my dear?" She turned to me with a sad expression and said, "Mommy, why don't people like me the way they like my sister? Is it because I'm not pretty? Is that why they don't say nice things about me as much?" I tried to explain to her, kissing and hugging her to make her feel better. Now whenever I visit a friend's home, I make it a point to speak to the elder child first. We can conclude from the passage that   _  .
