I always feel a little bad when UPS comes all the way out to my house in their big, gas-guzzling trucks just to deliver something mundane like socks — especially when I only paid around $2 for them after rewards points. I mean, yeah, $UPS is a major beneficiary of this e-commerce revolution that’s happening right now. But still, when I was a kid, having a package delivered was a pretty big deal. It meant something important had come. More important than socks, anyway.
