I feel like it’s less of having empathy for the other person and it’s more of understanding that the other person does not have the knowledge of the situation. Or does that have empathy for you. When i encounter rude individuals who will not let me finish my sentence or cut me off, I try to not take it to heart and I try to take the higher ground. Usually I’m just struggling on one word so when they cut me off I’m able to say something snarky back to them. It helps me feel better!! Also remember you don’t always have to stand up to people or be mean or snarky back. Taking the higher ground and walking away or asking them why they’re doing that should shame them enough so they think about their actions. I wish you luck.
