As a Boomer about Lynn’s age, the strip did a pretty fair job of tracking the stages of my life (OK, I’m a bit later to the grandchildren stage but close enough.) Perhaps the best thing about it is that it has a beginning, ups and downs, and a clear end with the birth of the next generation and the “he lived long enough to see his great-grands and died full of years and honor” (not a quote) epilog.
Too few authors know when to stop, and more honor to Ms. Johnston for the wisdom to do so.
