There’s something oddly tender about small things, isn’t there? Like when a newborn baby wraps her impossibly tiny fingers around yours and suddenly the whole world shrinks into that one little grip.

And funny enough, this idea of “small but meaningful” pops up in places you wouldn’t expect… even in something as plain as a length measurement.

Take 4 inches, for instance. Not too big, not too small just enough to exist without demanding attention, yet present enough to matter.
