是故父母之所愛亦愛之。父母之所敬亦敬之。至於犬馬盡然。而況於人乎（禮記。父母所當愛之。犬馬猶不敢輕賤之。況父母所愛之人乎）。

Therefore, what one's parents love, one also loves; what one's parents respect, one also respects. This extends even to dogs and horses, and how much more so to people! (The Book of Rites says: toward what parents love, even dogs and horses one does not dare hold in low regard, how much more so the people loved by one's parents!).
