Say this to mean that

As parents, we are important examples through which our children may see Christ-likeness. The other major environment which shapes my son's behaviour is school. We have placed him in a christian school in the hope that he may be exposed to christian culture. I am exposed to american culture a bit and also to american christian culture by listening to the christian radio program. I am concerned for my son that he does not understand absolute principles. When I say A, I mean A. When I mean B, I say B. But within the broader american culture, when they mean A, they say B to mean A. We live here in america and one day my son is going to work here and maybe marry here, he will have to say B to mean A. But I am concerned for him because I want him to learn absolute. I want him to say A to mean A also in addition to being able to say B to mean A. In one incident, he was saying something to me. With a change in phonetics, he meant it a different meaning, perhaps in a disrespectful way. When I confronted him by asking him if he meant A. He said no. After much talking to him and later in time, he subtly admitted that he meant A by saying B. Whenever there is subtleness and it is disrespectful, I will always have to confront him so that when he say B to mean A, he will have to say A to mean A to me or at least admit his fault even if it is by saying B to mean A to me.
