Every part of prom night is unacceptable here. It is like people of opposite genders (who have no relationship with eachother) being together for a night function. It is not seen as a socially acceptable act. Moreover, it is likely to bring questions on the character of people especially women.

P.S. It may be happening among some very upper class families with liberal social circle but they would hardly form 1% of our society.

@selfhelp4trolls , I realized one thing writing this. The cross cultural community is not only for understanding other cultures but is also an opportunity to examine our own culture critically. I will surely write in it. Thanks.
