The students who are pretty confident tend to come from normal families or have a mother with strong Chinese language skills. Conversely, children whose parents are divorced or whose father is away from home for long periods of time, or who are being raised by grandparents, tend to be shy and withdrawn.
有信心的孩子，多半來自正常家庭或媽媽語文能力強，比如那位很會鼓勵人的六年級姊姊，爸爸是船長，當初是因為漁船停靠印尼時認識媽媽而牽成姻緣；相對的，那位「臉苦苦的」男孩，父母離婚，因為爸爸長期在外地工作，由祖母撫養，覺得自己不如人而性格退縮。
