On my way home last night, just as I'd crossed the street and was on final approach here comes an elder and his son on the way to the meeting. As he spots me he gives me the wave, arm fully extended and moved left to right, back and forth, to and fro. I reciprocate with the same wave.
He looked like he wanted to come across the street and talk but didn't. He was actually one of the decent ones who acknowledged my brief presence at the meetings. I'm sure he reported his sighting to the PO and maybe they'll get up the nerve to want to make a shepherding call.
I can only hope so.
