Lots of people still ski for leisure, or for the exercise, or just to enjoy the splendor of the great outdoors. If this is the kind of skiing you enjoy, I would say just pick a pretty mountain and contain yourself to the green runs and you can have a very laid back day.
On the other hand, if you enjoy pushing yourself physically then skiing can also be a thrilling pursuit of your personal limits. When you are competing with yourself, trying to become better at a hobby you are passionate about, you can definitely become emotional and a bit tense.
There are a lot of people all over the mountain that take it pretty seriously just for the fact that it costs a couple hundred bucks just to rent the equipment and get an all-day lift ticket. If you make $1000 a week and you just paid $200 to go skiing, you might be a little bit annoyed if someone is stopped in the middle of the run to take photos, or skiing behind someone who is mashing the bumps down by side-sliding because they rode a lift to a run they couldn't handle.
