One thought on “Weekend miscellany

  1. Thank you for the seatbelt one. I had seen it mentioned before, but hadn’t yet watched it. I got tears in my eyes. It’s perfect. (I wonder if it works well for kids, too. I’d expect ads that get kids bugging their parents to wear a seatbelt to be wildly effective.)
