Don't teach Dhamma to those who can't appreciate it or aren't interested

I read in an answer that AN 9.5 states: > The best sort of kindly speech is to teach the Dhamma again and again > to someone who is engaged and who lends an ear. However, is there an opposite quote to this in the Pali Canon? Does the Buddha say anywhere in the Pali Canon that we should not bother to teach the Dhamma to one who cannot appreciate it, or is not interested in listening to it? What I'm asking for, is perhaps equivalent to the following quote from the Christian Bible in Matthew 7:6 : > Do not give dogs what is sacred; do not throw your pearls to pigs. If > you do, they may trample them under their feet, and turn and tear you > to pieces.
