"Honor thy father and mother"

 

 

Once they have their load of SexEd, your preaching of filial piety sounds really laughable.

Read them the Ten Commandments.  It says "honor" rather than "love".

Respect them as individuals, and let them know that you expect the same in return.

Be a competent parent.  Care about what they need and what they feel.  Impart your wisdom to them.

 

 

(LZ's point is well taken.  The "you" here means the reader.)
