"Susceptible days" include Valentine's Day, Chinese Lovers 'Day, birthdays, Christmas, the night before a boy goes into compulsory military service, and even the first date after a big argument. It is more difficult to keep in control on those days.
像是西洋情人節、農曆七夕，雙方的生日、耶誕夜、男孩入伍前夕，甚至激烈爭吵後的第一次約會等，都是最易令人把持不住的危險日子。
