I was just thinking last night about this and how I was dreading having to think about it. As usual the other members of GB have put perfectly into words what I think. Anytime I think about the loss of someone I think of that Chris Cornell song "Wave Goodbye". I hate to say that I hope it gets easier for you if it means losing touch with those memories, so perhaps I can just hope that instead you'll somehow maintain them only without the feelings of profound loss. I also wish I could say something more that would be helpful, but I too feel that I don't have the words.
You said "I can only hope to live a life that touches as many people as those two did. If I do a fraction of what they did, I’ll be happy." and I'd just like to say that I think you are well on your way sir, I don't think you'll ever have to worry about that. Best wishes to you @patrickklepek
