I was working in the back room of my house, transcribing an interview with Lara Logan (she's fascinating), when my dogs started barking at the front door. I ignored it for 30 seconds, because that's just what they do. Figured it was a cat or the mailman. But they kept on and kept on, so I finally walked to the front to see what was up and there were two teenaged Jehovah's Witness boys standing with their back to the door, just having a chat on my front porch. I was right behind them at the door and they never turned around, nor did they ever ring the bell or knock. It took them a good five minutes to turtle their way from my house to my neighbors.
I don't know why this made me so happy, maybe because it's exactly what I used to do when I was a JW and it's kind of nice to see how much they still hate preaching.
