When I say sorry to someone, maybe I didn't mean it because I dun think I did it wrongly. Maybe I just try to be responsible and admit my fault due to the virtue, ethics or morality shaped by the society, and I try to do sth which the society think is correct. So now when I do sth seems gd, for example helping others, I am not sure I really want to do that or I am just hypocritc, trying to be good and kind to the others
