Well I just got grounded for kissing a girl that I've been dating for a couple of months. My parents think I lied to them but I told them the truth. Im 12 and she's 12 but still younger. I don't think its fair because I see her a lot and now I can't talk to her without being scolded at Help

Your parents are protecting you, I am not going to waste my time trying to explain it, your parents are right, it was wrong, since kissing will start and lead to more and at 12 is not proper.
You are trying to act too grown up. Your parents are trying to teach you boundries and rules.

Accept it and go on.
