For many of us, it's oddly satisfying to see something very neatly arranged or that naturally coordinates its colors well. But it's also possible to be oddly satisfied by some of the little things we do.
It may not be possible to consistently draw a perfect circle, but on the rare occasions that we happen to do that, it's hard not to stare at our achievement for a moment. Even if nobody else gets it, it was satisfying to us.
Just because we may feel it the most strongly when we do something that fits this bill, however, that doesn't mean we can't get this feeling on a second-hand basis either.
Although some of the examples we're about to see are easier to explain than others, all will definitely bring up some unusual feelings.
