o bhai when two individuals who are independent or what not can date if they are sane and sound and wont use each other like paper towels mature enough , they dont need their parents permission to date or marry each other , obviously monitoring them is necessary , thats my opinion .
there is no issue with it regarding religion only the problem arises when if the purpose is for sexual experience .
no commitment for the future to whether both the couple will mary or what not or have kids or not or what both are gonna do or just create problems for the society or community , when a guy and a girl choose to live by themselves just for funnies it could only give a ton of a headache and more natural disasters hey , my opinion nothing else , no argument ,nothing .
