Is the girl who goes to disco a good girl?
First of all, you have to get to know her yourself. The key is to look at people, whether to go to the disco or not, perhaps to vent or like the atmosphere there, so as to hide yourself. Not all people in discotheques do dirty things. The key is to see if you can go into her heart and know what she is going there for. Even people in prison will be wronged.
