We travel a lot and used to make a point to try and catch a meeting.
We went by this one area every year.
1) 1st year, not a peep
2) 2nd year, only a poor brother that no one else talked to; he was desperate.
3) 3rd year, a sister with a non-jw husband and a couple of children. Was surprised we had been there twice before. I answered at the WT study twice and gave my name...she was the only one who came up to say hi.
Another congregation
1) a crowd of people saying hi, offering to go out to eat afterwards; found out there was someone there that had moved there from my circuit. A nice visit.
2) same response, friendly, wanting to catch up.
Another congregation
1) one elder came up and talked to us, turned out he was related a sister in my old congregation. That was it.
Circuit overseer story
The circuit had a new CO but no one had met him before. It turned out he was there a little early and decided to visit a congregation incognito. He and his wife were totally ignored, totally. He tried to talk to some of the brothers, but there were too busy for a visiting brother of dubious status.
Three weeks later he came on Tuesday night, his visit to this congregation. Ignored because they remembered him as that no status brother from before. He went up to the PO and introduced himself and then a flurry of introductions. That was back in the day when the CO had some leeway in his talks. It was about greeting new people and how Abraham entertained angels because of his hospitable nature.
(Hebrews 13:1, 2) 13 Let YOUR brotherly love continue. 2 Do not forget hospitality, for through it some, unknown to themselves, entertained angels.
