An attitude problem is just a choice problem that got comfortable.

What looks like a personality is usually a set of responses that worked once and then stopped being examined. The eye-roll, the shutting down, the going quiet were reasonable adaptations to something at some point. They stay because nothing forced a review, not because anyone decided they were right. They are more changeable than they feel.

Pick one reaction you are known for and try a different response exactly once, in a low-stakes moment. It will feel unnatural, which is just unfamiliarity rather than dishonesty. Doing it a few times is how the old one loses its automatic status.
