Why are some people indifferent to cheating?

What does it have to do with me? I’m not the relationship police. I don’t know why people do what they do.

Why do I care one way or the other what other people in other situations get up to? It’s completely none of my business. The desire to pry into and pass judgment on other people’s private lives and decisions are a good part of what is wrong with the country and the world.

I’m mystified by people who think this is their territory. It’s just not.
