What is "Modesty of Speech"?

Mother reads from The Christian Mother and The Christian Father, and answers questions from:

Bonnie in Lockport, who is concerned about Eucharistic Adoration with music and "entertainment";

Douglas in Ontario, who is wondering about detachment;

Irene, who asks about Fr. Chad Ripperger's situation;

Niall, who is upset about dogs being allowed at Mass;

Diane, who asks if Nicodemus was born again and Catholic;

and Chelsea, who requests an explanation of "modesty of speech".
