nope...cuz it confuses kids
i often see kids (my cuzins kids) asking their parents there why they were not invited to their parents wedding?
besides, everything should leads towards neutrality. whereas showing affection in public really is an extreme form of expression> tamasha lagana....as if you have no sense of "particularity", or carelessness even for ur own emotions.
I hope you are not looking for answer yourself, here.
You know why they weren't invited, right?
