Well,I think it really depends on the situation, but I think I would say no too. Frank is right. At that age, hormones are raging out of control, and you can get yourself in trouble in no time. I wasn't allowed to "car" date until I was 16. So, that meant I was never really alone with a guy until then. Not really.
At 14 and 15 years old, you think you know everything and you think your parents are evil, when in reality, they have "been there, done that" and know what the consequences are. I'm 27 and still have a lot to learn, but I am wise enough now to know that I should've listened to my parents. It would've made my life easier. Believe me, you don't want to learn everything the hard way.

I'm moving this to Chit Chat.
