Today, your business is your business -- and their business is their business. So keep your nose out of what's going on in other people's lives, or else you will get an earful from someone who feels like their privacy is being invaded and their actions judged. Stay focused on your own path. Keep your eyes straight ahead, and your feet pointed forward. Just keep marching along your own path. There's nothing to see here. Even if there is, you need to stay out of it.
