On 85

Today, November 20 he would have been 85. So in the A Frank Angle spirit, here’s a toast to 85.

        Beavis: Yeah, there’s like, too many of them and stuff.

  1. Frank, I’ve been meaning to come by and comment on this. I love what you do with the themes, turning that sadness on it’s head. I’ve read this a few times and it was important to me to make sure I got to a PC to let you know how important things like this are.

    • Mo,
      There’s no question that everyone handles loss differently. It’s never easy, but the best I can do is hopefully write or say something that triggers a movement forward for someone else. Thanks for commenting.
