My brother and I wanted to get pictures of the sunset, and neither of us wanted to walk into the water in the backyard because we've done a countless amount of times so we went somewhere close by the house.
I usually don't have people in pictures. I feel like it takes you out of the picture. But of course there is an exception. If the person in not the main focus, and does not have any great detail, then I would take the picture, and I think this is a good example of what I am poorly explaining.
