you have two choice
1st choice you should stop what are you doing for 10 days take a short break and think are you right to do that or your father is right that you shouldnot do that work.. Then you will find the answer by your self but 1st take a break to know the right thing when you be away from that work..
2nd choice and that I love it.. You stop now what are you doing and go to your parents and hug them big hug and love them do what they want they will be right but you cannot feel it because you are blind by your work or someone makes you love it that's your problem
