Not at a funeral but at a JW wedding the father of the bride was "allowed" to attend the ceremony at the hall. He couldn't walk his daughter down the aisle or the couple would have to find another place to hold the wedding and most of the guests wouldn't show up because of the father being DF'ed.
Later in the day when guests were invited to go on to the reception hall, a nice rented place outside of town, the father showed up and was immediately "stopped" at the parking lot by some of the friends of the groom who were asked to be on the lookout for him (and his new wife who was a "worldly person"). She could go into the place but he was asked to remain outside. He said he was going in anyway.
The place was very nice. The groom's family had put out a lot of bucks to rent the place and the decorations and meal were excellent. I opted to go for a little air outside while my wife and some of the gals had a hen session inside.
So, that's where I saw these friends of the groom blocking the entrance with their bodies and telling the father he'd have to wait a few minutes. One of them went in and told the groom, and that was pretty much the end of the reception for a lot of the invited guests since they were told that a DF'ed person was going to try to come in and if their conscience said they should leave then they should.
The father explained that he wasn't going to stay long. Just to come in and wish them well, give them a present they'd brought. He wasn't even expecting to stay for food or drink.
Well, it turns out the father didn't come into the reception hall. He was very upset, visibly so, his hands shaking and he seemed on the verge of tears. He was clearly not a violent person and it hurt him deeply that he was treated this way. The daughter came outside. They walked off into the parking lot among the cars together.
My wife wanted to leave saying that it wouldn't be appropriate to stay there if a DF'ed person was allowed in the reception place as we shouldn't even eat a meal with DF'ed persons.
I started to explain to her that the DF'ed person was the father and that it seemed he wasn't going to come in after all. But, to no avail.
As we got into our car I saw the daughter in tears. The father trying to reach out to her with a pleading expression on his face and his daughter swatting off his hand and looking away.
It was one of those moments that stick out in my mind as being part of my waking up to the reality of all the hurt this JW religion has caused families due to it's DF'ing policies.
