My mother and I had a conversation about tipping quite a few years ago. We have both worked as servers and tip well for full service. But we were at a serve-yourself buffet, where the waitress only brought drinks. I thought we shouldn't tip the same amount as for full-service. There was only one waitress bringing drinks for at least twenty tables, and I imagined her cleaning up at 15% of each bill. Mom said, "Look around at these people. You know almost none of them will leave a tip at all." She's got a point there, but is it our duty to make up for other people's bad tipping? I've never really answered that question, because the price of buffets has doubled since and I don't go to them anymore.

I think the constant, rhythmic movement matters more than the container. Babies sleep pretty good while someone is walking and carrying them. It can be a hassle for modern parents, but it makes sense from nature's standpoint.

I think he accidentally a word.

I assumed that he was the poisoner when I first read this.

You wouldn't believe the adventure I had searching for an illustrative picture of "two jugs."

Some of the painters.

And yesterday we had that post about a frog that incubates eggs in its stomach and gives birth through its mouth. Nature is, ahem, odd.
