I was in the same boat at her age. All my friends were 18, I was 17 and couldn't go out with them. In the end a whole bunch of us younger ones ended up hanging out a lot and getting up to mischief elsewhere. So I get how she feels...but essentially attempting to steal my identity? I just sat tight and waited, why can't she!
Apparently the other day she went out to some club with friends in the city and didn't even get asked, which amazes me. Every time I have been out we have all been checked and scrutinised up and down for a least 30 secs!

I told her she can't use my ID anymore and took all the bits and pieces she had collected and brought them home. So hopefully that is the end of that.
