Very nice....who could find fault really ? It does seem a bit ironic when we all know that in the past, this sort of thing wasn't allowed because it wasn't following the societies typical arrangement. Jehovah's house was a place of pure worship and not for use for our personal affairs and kingdom songs were said to be prayers to Jehovah rather than for use as way to woo your girl friend into saying yes to a marriage proposal so that you can later post it on the scary awful internet.
I'm sure if a young brother asked any of our local elders if they could use the hall to propose to his girlfriend, there would be a review of the couples "standing" in the congregation, are they regular in field service? Are they setting a fine example? Of course there would be a mandatory cross check of several decades worth of watchtower magazines to see what precedents had already been set and a call or two would have to be made to HQ back in New York.
Anyway, since the groom to be, invited a bunch of onlookers to witness his proposal and he filmed if for Youtube, I'm glad
she said yes ! It would have been embarrassing if she'd have turned him
down flat. Who knows...maybe she did later when they were alone.
