To wolf: Some crazy people have a problem with ketchup on shabbos.Because ketchup is not a “classy food/very weekdayish” and they dont want that for their precious child.It doesn’t fit with their ideal/their shpitz of a Shabbos meal!I seriously feel that some peole need to be certified.
I agree with you that we need single functions.However nobody wants to make them for the younger crowds.When I go to chasunas there are so many boys and girls.Let them meet with proper supervision for lets say dessert or right after the chuppa before the Chosson and Kallah come in for dancing.Or have some sort of speed dating thing.Where nobody has to commit to everything.There are lots of cases where a boy’s mother will say no to a girl because she dosen’t think that the girl is pretty enough for her “Moshe Rabbeinu”.However her son may feel diffrentley when he sees the girl.The girl is rejected by the mother while her son may think that she is gorgeous!
Don’t tell me that its untznius because I don’t buy that.In the time of Chazal there was something called Tu Bav.Where a girl was not judged by her yichus and money!The girls use to dance in front of the boys.I am not suggesting that.However a tznius meetings/events with supervision needs to be made.
