Why Josh Can't Be Left Alone

I went to a wedding last week, one of those really frum ones, where the couple are two people from normal homes, but want to be very chareidi, so they have a wedding that would make Gd proud. They had a Mechitza (divider) up that split the room in half and was at least ten feet tall. All good. Except that none of the guests were that religious. So co-ed mingling ensued non-the-less. You can't stop human nature...
