Yah. You know, I think the Funky Winkerbean strip was headed for something similar -- there were hints at times of such a reunion between the mother (one of the characters) and her baby given up for adoption many years ago.
But ever since the local paper shut down, I've lost touch with the strip. (Though I never forgave the paper for dropping Kudzu back in the late 80s /early 90s. Now it's gone forever -- Doug Marlette, R.I.P.)
