I don't let my DD do any of the above! Its got a little to do with her behaviour though, she hasn't shown enough responsibility to.

I can't stand 'hanging out' at the shopping centre, she goes there to shop and meet friends and work.
No riding in cars with boys! Well haven't crossed that bridge yet, but I'll probably take Mrsmacs attitude to that one, it will depend on the person that has the car.

What is it with going away for the weekend ALONE? My DD wants that too but I just laughed and said she could wait till she had a licence. We did briefly talk about it, but only so I could point out how no one would want a bunch of 16yos yahooing around their establishment, and the fact that most of her friends are pretty hopeless with responsibility and that she would get lumped with it. That worked.

Drinking - no. I'm sure she has had one or two when she has been at a party (that she gets picked up from etc), but I'm standing fast. Its been good because she has repeatedly seen how silly it is to spew in front of people. When she hits 17 I will review the rules.

Its all so individual, and it would be harder for you if DD is hanging out with older people. I'm not sure how I would handle it. I suppose I would hope that the people have some sort of maturity....

My DD is a 'young' 16 and not stupidly boy crazy thank heavens. She wants to achieve at school (after she threatened to leave home too for the same reasons), but I'd say that is through seeing her friends move out and have nothing, no boundaries and not much future. I've been sort of lucky that she hasn't pushed any harder.

good luck with everything.
