It seems that some listeners equate "happy" with "sappy".  While the program wasn't about a happy event, it did have a more positive tone and, certainly, a happier ending than most of the CBSRMT shows.  I enjoyed it not only because it had a positive feel and ending, but also because it was a nice break from the shows that don't end so well (the majority of the RMT episodes).  I think the grandmother really knew that her surrogate "Charity" wasn't her real granddaughter, but appreciated the kindness the girl showed to her in the last hours of her life.  Sure...a soap-opera-style approach...but an enjoyable one to me.
