Have you ever had someone who knows you well repeatedly ask you things to which they already know the answer?  Or, they may continue to try to involve you in situations you have absolutely no interest in doing or simply should not even be considering.  Not bad things, just events where you choose not to spend your time or situations in which you are not called to participate.  These are just a few examples.  The list is lengthy and can escalate.

These are manifestations of toxic behavior.  It is disrespectful of you.  It is rude at the very basic level.
