My parents were never hardcore about curfews and things. They had them and they enforced them but they never went overboard, in my opinion. Later on, when I was turned 16, I just went out whenever and I wouldn't say they didn't care but they never raised a big stink over it.

On the other hand... Man, I had some hellacious groundings over grades. If school was in and I wasn't 16 years old yet, you could pretty much bet I was stuck at home.
