Think BIG, thanks for the compliment about having a chassidische soul…
What you described about the kallah kissing the uncles and grandfathers on the other side is,obviously, wrong,especially in public. I have not seen this and mostly, the women are sitting on one side and the men on the other.. Wherever I have been, the kallah always stands still and the rebbes and the people dance in front of her. (Sometimes, the poor kallah gets all entangled in the gartel too..)As far as the badchan goes…he has to make a living and this is in line with the Amoroim’s “milse debedichuso’…
One last word about holding hands after the chuppah.I have heard, please correct me if I am wrong, that in Ger, they are makpid that chosson kallah hold hands after the chuppah.I don’t want to make mistakes about this, but it could be that this is done to familiarize choosn vekallah with each other.
