I'm Gretchen Rubin, and this is a little happier.

As I've grown up, over the years, I've noticed something that has surprised me.

The world changes more than I assumed.

When I know little about a particular area, it seems permanent and

unfaltering. When I look closer and when I know more, I see that there's much more change than I

The Nix. I wanted to see if I could make myself interested in a subject. Spoiler alert, I can't. Go Nix.

As I've been learning more about basketball, I've been struck by the fact that the rules change over time.

Without ever really thinking about it, I thought, well, basketball was invented in 1891, and sure, it probably changed a bit,

become unavailable when the Met is doing major renovations, as it is doing in several areas now. But even in

areas that seem set and settled, items come and go quite frequently. For that reason, when I visit
