My 9-year-old daughter, Susan and 5-year-old son, Robbie went to the shopping centre with me. As we got there, we saw a big sign. It said, "Petting Zoo". The kids jumped up and asked, "Daddy, can we go?" Both my wife and I were out of work. However, I said, "Sure", giving them a quarter each. They went away, leaving only fifty cents  left in my pocket. A petting zoo is an enclosure   for kids to play with little animals while parents shop. A few minutes later, I saw Susan walking along behind me. I was surprised and asked why. She said sadly, "Well, Daddy, a ticket for Petting Zoo costs fifty cents. So I gave Robbie my quarter." Then she said my family motto  , "Love is Action!" I knew no one loves little animals more than Susan. She often watched my wife and me do and say "Love is Action!", and now she had put  _ it _  into her lifestyle. It had become part of her. She knew not only "Love is Action!", but also "Love is Sacrificial   Action!" I was moved. We went back to the Petting Zoo. Susan stood with her hands and chin   resting on the fence   and just watched Robbie feeding the animals. I had fifty cents burning a hole in my pocket. I put my hand into my pocket and took out the money. Sure, I must do that! From the passage we can infer   that   _  .
