17．
At 18，many American young people go off on their own．They go away to college or find full-time jobs，and they often rent their own apartments．Some get married and start families．This independence（獨立性）is learned from childhood．
From an early age，American children learn responsibility（責任感）．Children as young as 2begin to put away their toys and dress themselves．At 3，many children do simple chores like setting the table．
Using money wisely is also taught early．As soon as a child understands the value of money，he or she receives a weekly allowance．This is used for things the child wants，like toys or treats．The child can spend or save it，usually with little guidance（指導） from parents．If the child wants money besides his or her allowance，it must be made by doing extra chores．
Children are taught early in life to think for themselves．They are allowed to make some decisions and make mistakes．Failure often teaches children more than success．
