As a teenager, I didn't quite get why the kids in Ferris Bueller's Day Off went to the art gallery. I mean, they went for an epic lunch posing as the sausage king of Chicago, they went to a Cubs game, they crashed a parade, it was all kinds of fun. But art galleries don't tend to be fun, and it didn't look like they were having fun, so I didn't quite buy that high school kids would go there on purpose.
Of course, now I get it. Life is empty without art, and that flick is about seizing the day and living life to the fullest. You can't do that without art.
