I wanna go out with my gf but my parents hate her, so I told them I was going out with some friends. I don't know if I should do it cause they are going with me and they usually take me to the place (go in the cinema with me, for example) and look the people with whom I'm supposed to do something. Should I risk myself and her by going out with her and try? Last time they stayed out the cinema for hours and we couldn't go in. My best friend covered us cause he went to the cinema and said that he spent the whole time with me.
Honesty is the best policy really. Why risk losing your parents' trust completely by lying about something like that - where you could very easly / likely be caught. Instead maybe you should have a discussion with your parents about why they don't want you to spend time with her.
