Is changing the subject to avoid being asked something you don't like a sin?

Just quickly changing the subject even if the changed subject doesn’t interest you and you just changed it for people or one man/woman to forget about the previous subject.

It may not necessarily be sin, in my opinion. It depends on whether you simply don’t want to talk about something, want to hide something, or intend to lie about something by avoiding the facts.

It depends.

Right. There is nothing intrinsically sinful about changing the topic of conversation intentionally. If you are doing it because the person is asking you something they have no right to ask you, then it wouldn’t be a sin in the slightest. If you’re doing it in order to avoid telling your spouse something they have a right to know, then it could be a sin…

If you do not wish to talk about something silence is golden. Not a sin.

Let’s look that up in the Catechism of the Catholic Church:

2488 The right to the communication of the truth is not unconditional. Everyone must conform his life to the Gospel precept of fraternal love. This requires us in concrete situations to judge whether or not it is appropriate to reveal the truth to someone who asks for it.

2489 Charity and respect for the truth should dictate the response to every request for information or communication. The good and safety of others, respect for privacy, and the common good are sufficient reasons for being silent about what ought not be known or for making use of a discreet language. The duty to avoid scandal often commands strict discretion. No one is bound to reveal the truth to someone who does not have the right to know it.

That says there may be good reasons to avoid revealing the truth. But check this out too:

2483 Lying is the most direct offense against the truth. To lie is to speak or act against the truth in order to lead someone into error. By injuring man’s relation to truth and to his neighbor, a lie offends against the fundamental relation of man and of his word to the Lord.

According to that, we also lie when we “act against the truth in order to lead someone into error.” What does it mean to “lead someone into error”? I think it means to lead someone to believe something that is untrue. It may also mean to lead someone to act in error as a result of not knowing the truth.

why do you think this could be a sin?
