Remember that episode of “The Brady Bunch” when Peter Brady met another student at school who looked exactly like him? I was reminded of that when my girlfriend and I drove down to D.C. this weekend to stay with some friends for the first time in about two years, we realized that their dog looked exactly like our dog. They weren’t perfect twins, but their heights, builds, and faces were within 90% of one another, to the point where it was often difficult to tell them apart without looking carefully. The uncanny resemblance entertained us all weekend, and we couldn’t stop talking about it, finding it endlessly fascinating. We’re totally dog people now.
