事雖小  勿擅為  苟擅為 子道虧

雖然只是一件小事，如果不合情理，不要任意去做。如果做了，就是不孝，因為父母不會願意見到子女做不合情、理、法的事情。

A matter might be trivial, but if it is wrong to do it or unfair to another person, I must not do it thinking it will bear little or no consequence. If I do, I am not being a dutiful child because my parents would not want to see me doing things that are irrational or illegal.

 (果立注: 勿以善小而不為。勿以惡小而為之。許多大奸巨惡者，皆由小惡開始。 修身首重修心。若能惡念不起，或者念頭一起，便能警覺，方得成效J

物雖小  勿私藏  苟私藏 親心傷

東西雖小，不要私自收藏。如果私自收藏東西，父母知道後，一定會感到很傷心的。

Even though an object might be small, I will not keep it a secret from my parents. If I do, I will hurt my parents’ feelings.

(譬如佛法，沒有經過同意，拿別人紙、筆，即犯盜戒。此與前段介紹的「事雖小  勿擅為  苟擅為 子道虧」相互呼應。)
