I agree it’s totally outdated, in a world where women are getting married later in life and have lived on their own for school/work, or are already living with their fiancé (like I am). Besides, the original reason for the crying is actually very unpleasant (fear, uncertainty about an arranged marriage, apprehension about leaving home) so I wouldn’t wish that on anyone in the 21st century.
But for tradition’s sake, I’m sure I can manage a tear or two to satisfy the gossipy uncles and aunties who will be there watching and judging ugh.
