Clyde is good friends with a long-standing JW. He was a PO for many years and now a widower in his 80's. I won't go into great detail, but will just say that Clyde has truly been his best friend in every way.
About a year ago, two elders half his age took him aside at the hall and counselled him to stop associating with Clyde as he was "bad association." I guess you would call that marking.
