I was very 2 to earn my own pocket money and my parents 3_ interfered(干涉) with how I spent it,even when I was spending it 4 . They believed that by eaming money, spending it, and leaming from the_5__ ,1 would become more mature (成熟的) and 6 about how to handle work,relationships with others , and money.
