My wife and I have similar shirts as the ones Hersch and Judy wore on their cruise, though ours specify, “Annoying Each Other Since 1974 And Still Haven’t Killed Each Other!” Our children are so embarrassed, but we don’t care. Like our fictional protagonist, I gave my wife hers on a cruise, and we got a lot of smiles and congratulations. We had a nephew help us with Photoshop. Art imitating life, or something like that.
Enjoy!
