Talking with my son - toy car My son is 3 years old. Two days ago in a shop, my son took a liking to a toy car. This toy car is $150 NT Dollar and he want to buy it . But I didn't buy for him. Because I want to teach him need to make a plan for spend . So I told him , "we don't have plan buy this toy car today. But we can save money for this toy car. Your father will give you $10 NT Dollar once a day. After 15 days , you can buy this toy car". My son was sad and crying. I stick to this plan and talked to him long time. He finally said okey. In today night , I asked to my son , "Did you have been taken $10 NT Dollar from your father today"？ my son said , "Why I need to take $10 NT Dollar" ?
