Love?

What is Christopher’s definition of love? Do you agree with it? What is your definition of love? How do people experience love, for example between parents and their children? Given Christopher's aversion to being touched, can he experience his parents' love for him, or can he only understand it as a fact, because they tell him they love him? Is there any evidence in the novel that he experiences a sense of attachment to other people?

• Christopher's definition of love is that "loving someone is helping them when they get into trouble, and looking after them, and telling them the truth". 
• My definition for love is that when people love each other, they worry about them all the time, wondering if they are safe, and they want that person they love to be happy even if they are not together.
• I believe that love can be experienced and shown through the actions the people. Like what Christopher said, we help others when they are in trouble. Also, we consider each other's likes and dislikes when we are doing something. For example, Christopher's father considers all of Christopher's likes and dislikes and creates a life easier for Christopher. Another example is parent-children love. The parents help with the children's living and help the children build their future.
• Christopher can only understand his parent's love for him as a fact, because his parents tell him they love him. He is unable to actually feel what love is like.
• In the novel, Christopher is not really attached to anyone. The people in his life are associated with him only because they help him fulfill his daily necessities.
